Sometimes I go looking through a shop, refresh the page a second later and ALL the items are gone? I look at every other non-user shop and they are all squeezed dry too.

I'm sure this doesn't just happen to me and that there is some reasonable explanation. What is that explanation?

That's normal. The shops clear their stock from time to time. ^_^ It's not a bug or anything, it just happens to prevent having 600 different items in one shop.

Thank you Yiri (:

I was worried it was someone with super restocking powers out to get us all.
