12/27/12: Order placed 12/13/12, 1 of 2 units received was DOA out of the box. Gainsaver refused to pay shipping cost for return even though they claim 30-day warranty and I paid extra for 3-year extended warranty. Two weeks after they received the defective unit back, they still have not shipped a replacement. Impossible to get hold of anyone on the phone. All customer service contacts must be via online "Service Request" form.
Second of the two units failed 2 weeks after delivery. Separate RMA request submitted via online form. Again, returning the defective unit within 30 days is at my expense. Good luck getting a response. I've ordered several times from Gainsaver in the past, but this experience shows they do not stand behind their products and do not provide service.
1/2/13: Possibly as a result of the poor review I entered at ResellerRatings earlier today, Gainsaver has unceremoniously canceled the shipment of the replacement iMac which was supposed to replace the defective DOA unit they shipped on 12/13/12. They refused to refund the shipping charge for returning the defective unit to them. They said they will credit the purchase amount of the canceled order (which was charged to my card on 12/13/12) within the next 2 weeks.
No word on replacement of the second defective unit which was shipped back to them and signed for at their end. Steer clear of this company. I certainly will. This was not my first order from Gainsaver, but after this treatment, it will assuredly be my last.
3/12/2013 update: Gainsaver finally refunded part of my $$ to my credit card for the two DOA Macs they shipped to me, but only after I disputed the charge with the credit card bank. They did not even attempt to replace the units under either their 30-day purchase warranty nor the 3-year extended warranty I purchased on each. They did not refund the full amount even though they shipped defective units, nor did they refund the shipping costs to return the bad units which they never should have shipped in the first place.
Had I not disputed the charge with the bank, I am certain they would not have refunded a penny. DO NOT do business with this company.
