Wow! I use designerexportsinc all the time! I've bought more than 10k worth of stock from them over the last 7/8 months.
I will admit though Mark has been terrible to pin down on delivery etc. I dropship through them. I had two orders delivered by them last week and I have 2 final orders to get through - I've just emailed him about those.
I had a massive job getting the 2 orders to my customers last week, because as stated, Mark doesn't do great communication.
Having read your post, I'm just praying I can get the final 2 orders out before I quit - I'd already told him that I was done dropshipping.
Really sorry you lost money! Strange Mark still delivers some orders - in his own time of course!!!
