How long does it take for the store to restock itself? I bought some stuff just to make room for things I need like repair items, but the shelves still sit empty.

It should be every 8 hours (updated in 1.00.01 - was every 12 hours) if you're not pausing the game at all. If you pause the game, you may extend the time it takes to restock store items.

Thank you very much!

Does it only restock the spaces of item you purchase? Or does it randomly change everything?

It randomly changes everything, whether or not you've purchased any of the items there.

thats good Lady! i would buy things just to make empty slots b/c i thought it only restocked what u bought! thanks!

Yes thanks Lady that was also one of my questions

It takes 8 hours for the varied items in the store to restock or change. I had noticed it took around 8 hours but I wasn't sure so I timed it and it took exactly 8 hours.

Thank you Gypsy - at least we know how long it takes now. I have been playing for 3 days and I am still waiting for tape to fix the hose.

I see that it's been changed to every 8 hours for 1.00.01

I'll update my answer above, so that it's clear.
