[TYPO3-shop] demo/test mode for tt_products

[media.res | Alex Widschwendter]

hi all,

i imagine that some time ago, i saw a setting to put tt_products in test 
mode (so the basket is not cleared on checkout).
mainly i need it to style the "thx for your order page" without making 
50 checkouts ;)

so anyone?
