Procter & Gamble don't quite give out the same number of samples and coupons as they used to, but it's worth mentioning that their free P&G Everyday program is still alive and kicking! Actually their freebie form seems bugged at the moment, but it was working earlier this week and has been around for a few years, so I have faith they'll get it fixed.
Wait, what? Where was I? Oh yeah, the free P&G Everyday whatchamacallit. You can print coupons from there and request freebies multiple times a year. It's definitely worth having a free account already set up since their freebies tend to go fast.4
