Yes.
During some holiday promos you could get 1600 ms pts for about $15-$16. bucks. If you do the math, dollar per 100 ms pts is a pretty good deal. The MSRP on 1600 ms pts pretty much everywhere is $19.99.
If you can wait til TRU's B2G1 free promo next week, and want to chance it you should be able to buy 2 ms pt cards and get the 3rd one free.
