Most of Sunflower's purchases were in the form of gifts for other ponies, apparently. Twilight helped to advise her on purchases for some of her friends, including an apple brooch for Applejack and a super-deluxe Wonderbolts gift pack for Rainbow Dash. They stopped in a party supply store for Pinkie Pie. There was also one store, a curio store, where Sunflower had asked for her to remain outside. Obviously, that's where she was planning on buying gifts for her. She pretended she didn't know, and Sunflower pretended that she didn't know that she knew.
