Five good cigars shipped for $20 is a little much to ask.

www.esmokestack.com sells five packs of stuff for a good price.

www.jrcigars.com has a wide assortment of mainstream cigar 5 packs.

www.rockyscigars.com sells 10 packs for a good price.

Buying singles on-line doesn't seem worth it to me. You can buy them local for the same price and not pay shipping or worry about damage.

Also, I've found that many places use the "sampler" as an excuse to ditch unpopular cigars. You'll get a couple of good ones to sate you and the rest will be mediocre at best.
