Walmart claims to have great prices, but I disagree when it comes to Staples. I went in one day expecting to pay a whole lotta money for a whole lotta CD-R's, but lo and behold, I was flabbergasted. When it comes to reasonable prices they even beat the competition.
I was in and out the door with 100 cd-r's for only 20 bucks. Looking around my nexk of the woods for cd-r's was more steep at other stores in my area. So you can bet I walked out with a smile on my face that day.
In fact, the young lady who helped me was very sweet, and the CD-R's came highly recommended from her. She told me she uses them herself. You can't get that kind of service anywhere these days.
So in my book, Staples is not only the cheapest, but they have the nicest staff I have ever encountered.
