I sincerely hope that all this discussion was prompted by megative feedback on a few greedy sellers. That is exactly what I was hoping for.
And, if it was triggered by neonites's attack on me, that's just poetic justice. :-)

I only sell chips when I have accumulated enough duplicates to make it worth the trouble listing them.

My personal approach to shipping:

Usually $1.00, sometimes $2.00, for the first chip, and $.50 for additional chips, UP TO A MAXIMUM OF $5.00.

IMHO anything over $5.00 TOTAL for shipping chips is pure greed!

If your actual shipping expense is more than $5.00, and you didn't make enough on the sale of the chips to cover the shipping, then you REALLY should be doing something else!
