Hmmmm
Have you tried
lightningboltstudios.com his super model pack has things like tv dinner's and noodles, there is a fridge in his pack but the type you see in a kitchen... But there is also a mop and bucket that you would see in a store and certianly the pack doesnt have everything your asking for but it does have a few things plus a few things your not asking for that may come in handy like bathroom stuff.
You may also want to consider raptors website he has a bikerack plus other goodies on his site that may or may not go with your store idea here is
Raptors Site
You may want to also try
Templar Site
And here is another excellent resource
xplosys web site
If I remember right there are some glass doors that would probably go with your idea to here at
Wembley's Web Site
I don't know of a place that has a shopping cart or store refridgerators but magicfps allows you to build box's to the size you want with a nice texture map thats easy to follow as far as putting your texture on it you may want to look into that as far as making your own store refridgerator... Good luck with your store...
If you think education cost so much you should see how expensive ignorance can cost you
