If you don't already know, once a quarter, you can select free samples and coupons from Procter and Gamble's website here.
The following samples are available now:
Pantene Pro V Shampoo and Conditioner (comes in travel sized bottles!)
Head and Shoulders Shampoo and Conditioner (comes in single use pouches)
Prilosec OTC (If you answer that you suffer from heartburn)
Always Ultra thin and Dry Liners Plus
Tampax Pearl and Tampax Compak Pearl (I believe you get both!)
There is only one coupon available to select and it is for $1 off Cheer.
Here's the fine print on how this works: "P&GbrandSAMPLER allows one order request per household address per quarter. Ordering periods are generally between January 1 and March 31, April 1 and June 30, July 1 and September 30 and October 1 and December 31. Sample and coupon selections change throughout the year."
