Questions about Kroger P&G buy 4, Get $4

[snicketmom]

Is there a limit to the number of $4 off you can get in a transaction? For instance, if I buy 20 P&G products, can I get $20 off? Also , is there a list of participating items anywhere? Can you use that $4 towards the purchase of alcohol? Thanks!

As far as I know there is no limit. I purchased 12 today for a total of $12 off. Participating items may vary by region but mine had Tide, Downy, Cascade, Crest Pro Health Rinse, Aussie products, Cover girl, Charmin, Puffs, Always. (possibly 1 scent of Olay bodywash also) There may have been more but these are the ones that I remember. The $$ just comes off your total order so I wouldn't think it would matter what other items you purchased (alcohol included)
