PC Micro Store takes 40% off Apple iPhone 3G / 3GS Design Cases
via coupon code "40OFFIP3GDES". With free shipping
, most items are at or near lowest-we've-seen prices. (We saw this same coupon last month, since expired; however, each purchase also included a free screen protector.)
Notable after the coupon above is the Aimo Apple iPhone 3G Rhinestone Case (pictured) for $7.77 with free shipping. That's $5 off list and the lowest total price we could find.
