Okay I so I just bought one item from the main shops and I get 11 events telling me I had achievements for 5-1500 items bought from the main shops.. Does this also count items bought from the shops before this achievement was released or is this a glitch...? [edit]Question answered please ignore this thread!

I got that too, so I don't think it's a glitch...

It counts items bought before since its kept track of on the restocking royalty trophy on your profile!

Oh really? I thought it might be that, but wasn't totally sure.
