Fairytale Deals
Throughout the realms, Rumpelstiltskin became known as a being of great power and fear, able to grant a person's deepest wishes and darkest desires with magical deals that proved to be worse than he would intially proclaim. These deals appear to transcend into the Storybrooke reality as well, with Rumpelstiltskin's counterpart Mr. Gold retaining a similar disposition for swindling people in desperate situations. In either reality, it appears that Rumpelstiltskin always benefits in the long term through his deals, despite short term set-backs brought about by certain individuals.
The Dark Curse in Exchange for Riches and Comfort
In exchange for the secret to completing the Evil Queen's Dark Curse, Rumplestiltskin demanded riches and comfort in the real world of Storybrooke, and that the Evil Queen has to give him anything he asks for as long as he says "please." ("The Thing You Love Most"). It is known that Rumplestiltskin's counterpart, Mr. Gold, remembers making this deal probably because it was initially his spell that he gave to the queen, and is shown he remembers after Regina demands his real name with which he answers "Rumpelstiltskin". ("Skin Deep")
Marionette Potion in Exchange for Jiminy Cricket's Parents
In the episode, "That Still Small Voice," it is revealed that Rumplestiltskin had a business relationship with Jiminy Cricket, who would bring him possessions stolen by his parents during their travels as puppeteers in exchange for Rumplestiltskin's gold thread. One day, sensing that Jiminy had become disillusioned with being forced into a life of deceit and thievery, Rumplestiltskin offered him the chance to escape by giving him a magic potion that would take care of his parents for good. In return, Rumplestiltskin only asked that he be given Jiminy's parents after they had taken the potion, as it would count as his fee. However, Jiminy's plan backfired when his parents switched Rumplestiltskin's potion with a bottle of rainwater they had planned to give to another swindled couple. After learning that the couple had been turned into marionettes through the potion, Jiminy left his parents and made another deal with the Blue Fairy to become a cricket in order to mentor the couple's now orphaned son, Geppetto. Meanwhile, Rumplestiltskin, true to his word, took possession of the marionettes, who were later shown to be owned by Mr. Gold in his pawn shop in Storybrooke.

He returns to claim his prize from the regretful pregnant Cinderella.
Rumplestiltskin's Freedom in Exchange for Prince Thomas
When Cinderella confesses the terms of her deal with Rumplestiltskin to Prince Thomas, he concocted a plan to trap Rumplestiltskin. Thomas gets a red quill enchanted by the Blue Fairy that will freeze and neutralize the magic of anyone who uses it. Cinderella tells Rumplestiltskin that she wants to make a new deal with him. She tells Rumplestiltskin that she is pregnant with twins, and she will give both children to Rumplestiltskin in exchange for good crops in Thomas' kingdom, if Rumplestiltskin will sign a contract using the red quill. (The deal is a ruse; Cinderella is not pregant with twins.) Rumplestiltskin warns Cinderella that she should not try to trick him because "all magic comes with a price," but he signs the contract nonetheless. The quill freezes Rumplestiltskin and he is imprisoned in the dwarves' mines. However, Prince Thomas mysteriously disappears. Rumplestiltskin tells Cinderella that the Prince wouldn't return to her until Rumplestiltskin's original deal was honored. ("The Price of Gold").
Prince James in Exchange for the Location of the Fairy Godmother

The twin brother takes on the identity of his slain brother: Prince James.
Potion of Forgetfulness in Exhange for a Lock of Snow White's Hair
In the episode "7:15 A.M." Rumpelstiltskin made a deal with Snow White in exchange for a potion which would allow her to forget her memories of Prince Charming so that he would be able to fulfill his responsibilities to his father's kingdom.

Protection from the Ogres in Exchange for Belle
In the episode "Skin Deep" Rumpelstiltskin made a deal with with Princess Belle that she should forever be caretaker of his estate in return for protecting her father's kingdom from the ogres. Through her stay in his castle, Belle learned that Rumpelstiltskin had once had a son who shared his kingdom, but now had left him all alone, causing him to seek company which Belle could provide. Rumpelstiltskin later broke this deal himself, releasing Belle from their arrangement after suspecting that she was in league with the Evil Queen planning usurp his power and kingdom. This assumption turned out to be false. The Evil Queen had manipulated Belle into kissing Rumpelstiltskin and having him be cured of his evil by the magic of true love, a spell which Rumpelstiltskin resisted, believing himself to be unlovable.
Snow White's Location in Exchange for Prince James Cloak
In the episode "Heart of Darkness" Prince James demands Rumpelstiltskin tell him where Snow White is upon learning of Snow White bloodthirsty acts against the Queen. He agrees, but only if he will give him his cloak, claiming it is drafty in his castle. James takes off his cloak and Rumpelstiltskin show him a map of where Snow is. James leaves and Rumpelstiltskin picks up the cloak, smells it then leaves. He later pulls hair from the cloak and puts it in a bottle with Snow White's hair to form a true love potion.

However, it is learned after Emma is elected that Gold had always planned for her to betray him, realizing that standing up to him publically was a greater feat than standing up to Regina as it painted her as being brave and selfless.

After negotiating with Regina for the land necessary to construct a children's playground, Mr. Gold sells her a small plot in Storybrooke's forest, stating that he owns a sizeable amount of acreage surrounding the town. At the time, Emma Swan and Sydney Glass suspected Gold's payment was embezzled from the town by Regina so that she could construct a second home, but it turns out the whole deal was a ruse so that Regina would be able to deflect public suspicion from her shadier actions and have a legitimate reason to keep Henry from spending time with Emma. Wanting to keep his business transactions private, Gold never asked what Regina wanted the land for, but probably suspected her intentions nonetheless. ("Fruit of the Poisonous Tree").
Monetary Loan For Moe French
