Well, it depends. Ususally, when the stuff in the store runs out, or is low, there is more availible. It depends on homw much you have bought. For example, you can usually buy some kind of treat, like candy, in the beggining. Then, as you buy more and your tama gets older, more things that are useful, like a shovel for digging and finding things, will soon be availible. I hope this helps! If you need any more help, you can PM me and I will try my best to help you!
