Walmart has double edge razor blades for $1.76 a ten pack. A much much better deal than Walgreens. (more than $7 for ten)
The brand is wilkinson sword. I tried it today. It gives a very close shave seems to be sharp, but I had cuts one my neck, that I usually don't have. I used the styptic pencil, which stings but rapidly stops bleeding.
I'll be comparing the gillette, wilkinson sword, and astra over the next few weeks.
They cost 25, 18, and 10 cents a blade respectively.
