A big fan of discount codes? pchub.com offers three. Enter "pchub" in the discount code field on the order form for $10 off your first purchase. There is no set minimum, although you can't make money. Enter "pchub20" to get $20 off on any order over $200. Or, enter "ship820" for free shipping. Only one code can be used per order. The $10 discount may be most helpful when applied to inexpensive software, cables, and DVDs.
