The other night (around 3am), I chose a design and placed an order for business cards with VistaPrint online. Being an idiot, I accidently put the incorrect postcode on the interactive mock-up, proofed it but didn't catch it. I confirmed the order and paid. After printing out the design and info, I realised what I'd done. Checked the FAQ and realised there were no changes allowed after submitting. I did send an email asking if a change could be made prior to printing (possibly a bit SS). However, after that, I decided to bite the bullet and submitted a new order with correct postcode and paid for it.
Today, I received a reply email, refunding the original order cost, with a lovely screed from their customer service department, hoping my experience was good, and that the refund should be credited in a few days. I checked and it's already back in my account!
To my mind, that's exceptional service! I was entirely at fault, and they went above and beyond with their service. Given this,I'd happily recommend them to anyone wanting easy, no-fuss online design for business cards and related products. Very happy!
