Here is the ultimate Reccetear strategy: lose on purpose the first week.
You're thinking whaaaa? But get this. First of all, if you lose you get to see the awesome cardboard box ending.
Secondly, if you lose the first week you get sent back to day 2, and your wallet is reset. However, the shelves in the store keep all their items. Just play like normal, but make sure the shelves are stocked with expensive shit at the end of the final day of week 1 when you lose. then you basically get to start week 2 with a huge leap forward. That huge leap will carry forwards exponentially into the future weeks making the game much easier. I ended the 30k week with almost 50k, for example. The major bonus is that it buys you a bunch of extra time so you can go adventuring.

I predict I'll be done with the game by the end of the weekend, I failed at the last week (returned with 270k of goods) and have restarted for a third run. The game at this point for me is mostly figured out, and I'll be surprised if I don't far exceed the final weeks goal this time. On a related note, when you lose don't bring back only expensive stuff, it won't really get bought until you've re-established customer loyalty.
Also, what do the little gems you suck up during adventuring do?
Keep:
All items
Shopkeeper level
Adventurer level
Expansions to the shop, and any other benefits of shopkeeper level
New flooring, wallpaper, carpets, etc.
Lose:
All pix (start over with 1,000)
All adventurer cards
All unlocked dungeons (?)
Customer loyalty.
You also get one free adventure with Louise after each loop, in the proving grounds.
Yes, the stones are just XP.
