[TYPO3-shop] Articles (variants with new prices) & tt_products 2.7.1

[Tymoteusz Motylewski]

Hello
Has anybody articles (variants with new prices) working in tt_products 
2.7.1 ?
I've done everything form manual and still it's not working. I just want 
to be sure that this feaure is really working, before I start debugging.
Maybe anybody knows any tutorial or can share working html template for 
this feature?

Thanks!
Tymoteusz
