Kroger has Splenda on sale for $5.99, which is the same price as their store brand sweetener. The Splenda website has IP's for $3.50 off 2 bags of this size, so that makes them $4.24 each when you buy 2. I use lots of this stuff, so it's a good deal to me.
I actually just did very well at Kroger. Check it out:
2 Splenda large bags $11.98 - $3.50 Q = 8.48
1 Dentastix $3.59 - $2.50 SC - $2 Q = neg .91 MM
1 birthday card (sorry I forgot, Dad) = .99
2 Trident gum packs b1g1 $1.19 - $1/2 Q = .19 (less that .10 a pack)
5 Kroger Lite Yogurts $1.56 - .55 SC = $1.01
I got everything for $11.46....not shabby considering the number of times I've paid $7.99 for one bag of Splenda.
