So you have two choices on Revain, you can buy 100 of these for $4.95 or 4 for $1.99. This is an internal dilemma for several reasons: 100 at $4.95 = $0.0495 per Cap4 at $1.99 = $0.4975. You can see the value in a 100 pack, but who needs 100 unless you own a bike shop or used car dealership! However, if you buy 100, you'll have enough to last you a lifetime of valve cap needs. Of course, if you can last that long without losing them. In general a good product.
