In my pre-stockpiling days, I pulled a muscle. I was complaining about it to someone who suggested I put rice in a sock, microwave it, and put it on the pain.
I did it, and if I get through my Thermacare stockpile, I'd do it again. But CVS keeps peddling Thermacare wraps, so I may never deplete my stock.
This week, single wrap packs [[they're trial size]] are giving back $2.49 in ecb this week [[ending 06/27]]. What's nice is that they're only $2.49 to start. So, yup, free. There's a limit of two, which is nice.
Even nicer is that there are coupons out there [[insert and printable -- we've got all of 'em in our database]] for $1 off, turning these into a moneymaker. All that's left to do is wait for the pain.
