What I have done in the past is bought in bulk from eBay. There are some "generic" blades there that are very inexpensive, but the ones I have opted for are the name-brand Olfa blades.

Here is an example of the "generic" blades on eBay (10 blades for $8.45, free shipping):

Here is an example of the "lot" size I usually buy on eBay (15 blades for $30, free shipping):

Edit: I just realized that at least the second example above is still in the bidding process. What I usually do is click on "buy it now" to compare prices. I used to be able to get large lots of Olfa brand blades for about $1.50 each, but now they are running about $3 each.
