I ordered a large print from MPIX.com (20" X 30") for a client and it was shipped promptly as usual. The print was picked up yesterday at the post office (3 days turnover).
Unfortunately I chose USPS priority delivery, and regardless of the extra careful packaging and warning, those nice people at the Postal Services must have put some very heavy boxes on top of mine bending it and ruining the photo inside (that was sandwiched between 2 thick cardboard sheets). I emailed MPIX asking if they had any delivery insurance on my package and I got a reply about 3 minutes later from customer service saying they would replace at no cost. I emailed back asking if I could pay extra for FEDEX delivery since I don't trust USPS doing a good job (we know they really don't care about their damages since they cannot be held liable) and customer service offered free FEDEX delivery. So, just a few minutes ago somebody knocked at my door and it was FEDEX with my photo, delivered in perfect conditions and overnight.
I know this might sounds like advertising, well, why shouldn't it be? I used MPIX for 2 years for all my large print jobs and every single time they delivered (quite literally). Customer Service has been nothing short of amazing and now my photo is ready for matting. If we all share good and bad experiencing we can make our life as photographers a bit easier.
