We’re always looking for the best price we can find on a new T-Mobile handset and Costco has certainly gotten our attention with a $69.99 price point on the Galaxy S Blaze 4G. Good for new customers, upgrade eligible customers and add-a-lines with a two-year contract extension, the Costco price is the best offer we’ve seen thus far from a brick and mortar place. Given that T-Mobile’s $149.99 price comes after a $50 mail-in rebate, Costco is looking better and better. If you’re looking to pick up the Blaze 4G in the coming days, it looks like a trip to Costco is the right move.
