Ok, so yeah, i'm a white level and most likely you won't read this, but here goes.
Okay, so how about abolishing carry-over, and replacing it with a kinda' rewards system, which could work in a similar way, yet it's more fair?
Well, the idea is that like, the top three shops of one week, get a small advantage the week after, so it'd be something like this really:
1st place - (the current T$ prize) and 33 stock.
2nd place - (the current T$ prize) and 32 stock.
3rd place - (the current T$ prize) and 31 stock.
Doing this, it doesn't change the format much, but it does make it fairer for those who wish to compete in the shop game, yet still keeps the successfull shops with an advantage, 'cause as of now, it looks as though the actual competition side of shops has been erased due to carryover.
(btw, the extra stock only lasts for the week after your placing, so like, your amount of stock could change each week!)
