Query: You can never have enough of these!

At my day job we are always stealing jumpers from old equipment to use on newer equipment. After doing a little looking around, and realizing we could get 100 of these for this low price, I bought them. Our computer supplier, CDW, offers these, but their price is 3 times what they sell for on here, and that is before their exorbitant shipping costs. Buy these on Amazon and save yourself time and money.
