I first tried material world when they started - it was a quick turnaround offered within week.
Now years later I sent them 10 items, they received my package on November 1st - sent an email saying it would be 20-30 days before offer. Well it's now January 10th and I still have not received anything. I have emailed multiple times and they respond quickly saying that they are having delays. Last time they said I would receive my offer in 2-3 days. Well that was 2 1/2 weeks ago- don't waste your time
