I ordered a single studio pouch from Redbubble in on August 6th of this year. The manufacturing time was four days, which was satisfying enough, and my order was sent off on August 10th.
I live in Slovakia, and expected my package to take some time as they usually do - delivery times from the US for me have ranged anywhere between one and three weeks, so I was ready for a long wait. I ordered it about a month before I was set to move abroad, but I figured it'd still make it here before I had to leave; it didn't. It took more than two months for my order to arrive, and I had actually given up and thought it stolen or lost. I received it in early October, long after I'd moved away, with no explanation as to why it took so long.
Love many of the artists and items Redbubble offers, but I will not be ordering from them again.
ETA: I received a full refund of my shipping costs after I wrote this review. I have to say this impressed me; I have upped my rating by one star.
