I ordered a simple manufacturer-brand laser printer toner cartridge. CompSource had the best price, the best website & was able to tell me, with expedited shipping, exactly when my delivery would arrive BEFORE I placed my order. With others, you first have to place the order before they tell you when it will arrive. The confirmations, tracking info, packaging & follow up were all perfect. I will be back again & again! CompSource is an oasis of assurance in a sea of other merchant's broken promises.
