Staples: Charmin Basic - 32 rolls for $8.98

Head over to Staples.  You can buy a 16 pack of Charmin Basic Double for just $4.99.  This offer is good from now until July 30th.

Use a manufacturer's coupon and the deal is even better:
Charmin Basic Bath Tissue – 16 Double Rolls $4.99
$1/2 P&G 6/5 (exp. 7/31)   (this is why you buy sunday papers and hold on to the coupon inserts)
Final Price: $4.49 each wyb 2 ($ .28 each)

This is even a better deal:
Staples has a coupon good for 15% off on your in-store purchase.  Go here, print it, take it with you and you will end up paying $4.24 ($ .26 each) without the coupon, or $3.74 ($ .23 each) with the coupon when you buy 2 packages.
