To preface this: I am a marketer who deals with professional printers on a weekly basis, but for something for a personal side project I decided to try out a different supplier and thought i'd give Instantprint a go.... huuuuuge mistake. The uploading and proofing process was so complicated and un-user friendly, the results were inconsistent and and the customer service was appauling. I ended up cancelling half our order, but had to pay for one set of flyers that they had already printed (they were the only ones they hadn't sent us a proof of :/). The woman we spoke to on the phone was incredibly unhelpful and rude, and just kept repeating the same thing. To top it off I come on here and read reviews that the quality of the products is awful, so now I'm dreading receiving the ones that we did end up having to pay for... really wish I'd stuck with a supplier i know.
