WirelessAdvocates.com offered a rebate of a $100 Costco store cash card via the Costco wholesale website if you pre-ordered an iPhone S model cellular phone with T-mobile service. This offer was in print on the Costco website. When the rebate arrived in the mail it was a $25 Costco cash card and a cellular phone car mount. The page enclosed in the rebate envelope details what was in the package accurately, however this simply was different from the advertised rebate.
