My Walmart has had plenty of clearance Reactine lately. (Not so much since I've been there!)
Bonus packs of 20 + 20 (40) are 7.00 and 48 + 3 + 3 + 3 (57) are 10.00.
When I was there the other day, I only had 2 x $2 off coupons (I didn't know about the printable coupons at the time), so I got 6 packs of the 40s minus 2 x $2 for 38.00 total. that's 240 pills for 38.00, ~16c per pill.
When I found out about the printable coupons, I went back for 3 x 40s and 1 x 57 minus 2.50 x 4, which was 21.00 for 177 pills, ~12c per pill.
Normally I get 72 Exact brand cetrizine hydrochloride (which is what Reactine is... Exact is the cheapest generic brand I've ever found) for 17.00 or so, which equals out to ~24c per pill, so this Reactine deal is a huge deal for me. I want to compare the usual price of Reactine, only I don't know the usual price off the top of my head and it's not in any ads this week, so I'll go with a price I found out an online Canadian drugstore: 48 Reactine pills = 32.99, or ~69c per pill. The smallest box you can buy, 10 pills, is 9.99, or $1 per pill. And if that isn't the worst you can imagine (well... the worst *I* can imagine... but clearly I'm fanatical about it), consider other allergy medicines such as Aerius, Allegra, and Claritin which break the $1 mark. Just for kicks: if we assume that 48 Reactine normally costs $33 and I got 417, the total regular cost of what I got would've been over $285. Forgetting taxes (which would dramatically increase the difference), the amount I saved with this deal was over 226.00. My chest, throat, eyes, and the rest are saved for another year (expiry is July 2010 and January 2011, btw).
(The reason I bought so many is that I have cat allergies + 7 cats. I have to take these daily, which really adds up. I went to the trouble of figuring the math out because I don't think I've ever bothered to do it and was curious.)
