I purchase mine wholesale from a CT member, because I do Soap and B&B, I sell them for $1.50 for 1 or 5 for $6.50, they are a little over an ounce. They are far better than anything you can get in a store, they are not just plain tarts they look more like food. Now, I don't have a store, just my site and shows but if I did I would sell them for more to defray my overhead. Tarts are big sellers for me, I sell the warmers and tarts, I always include a free tart with the purchase of a warmer. Everything that has been said is true, you should reconsider recalculating your cost etc because even if it is a hobby you could actually end up losing $$$ and what will your customers say when you have to raise your prices by 25-50% after you are already in the ballgame?
