...and RMA-ing from TnT is a rather expensive process. The kind of cost involved to ship a product back to the manu borders on ridiculous. If its a really heavy product like a PSU, you lookin at prices north of 700 TT....and don't forget, if you get a replacement, you have to pay to ship that back here too. You can easily see how the costs begin to add up.Most times its just easier/cheaper to buy a new one and done.
This is why you need a fedex account and pay small money for 7 days shipping
