As I craft many small (and larger) items for XP, I think it would be beneficial to sell smaller items (i.e., party poppers, spells, fireballs, etc.) in bulk such as x5 or x10 at a time on a table vs having to place each individual item (such as bundling x5 party poppers and it only taking up one space on a table). This would also be beneficial for seeds in-game outside of the shop tab marketplace. I think this would save space in shops and when we want to buy items w/o clicking one at a time!
