Okay, so I bought my first floor repair kit from the store, but how do I repair the others? Spoilers welcome:) Is it correct that like all the other items they will pop up sporadically in the store? So slow....

One thing I wish we could do is set it on fast like we could the Virtual Villagers series, is there any possibility we could do this in another version?

Yes they will pop up in the store. I have been waiting for the floor kit repair since the beginning. Last time the store updated after 19 hours !!! I mean real life hours! It's incredibly slow and boring ...
I have no problem in sparing money

The game isn't intended to be over in a few hours. Like the VV games it takes time to develop. Some improvements may not be possible until the second generation of peeps, or even later ones. Patience!

It allows me to always have something to look forward to, so I'm not bothered by the slowness.

I think the store items change every 12 hours or so, so you just have to keep checking back.

12 hours?

12 real life hours. I general buy stuff I plan on using eventually, just to open more slots in the Misc. section to get re-filled.

I don't know if I just happen to get the same stuff twice, but it seems the Misc. section only gets new stuff If I used things from it - other than the outfits for the Adults changing.
