I've bought a couple of items from them. Pretty sure it's flat rate $4.99 shipping for everything. They aren't the fastest to ship but I've gotten everything I've ordered.
I have had a lot of trouble. 60 days and I am still waiting for a refund. I returned the item exactly as they directed. After 30 days I emailed and was told it would arrive within 14 days. 3 weeks later still no refund and now they say it never arrived. NOW they are not returning my emails.
