I recently ordered some glass for a friend, all from Stevenlmz79. I contacted them before submitting the order and expressed desire to have UPS shipping on all items (my friend's request). They asked me to submit the order, selecting expedited shipping on each item, but not to pay. It took some time for me to figure out how to order from DHGate without paying, there is an option to pay via DHGate and that made the order go through.
Stevenlmz79 then updated the invoice total with a new adjusted cost for UPS shipping, which I didn't have to pay until after items were received. Was expensive, like $60 for 4 items, but Stevenlmz79 had decreased the shipping cost by half and I had the items in 3 business days.
Every time I order from DHGate I try to order multiple items from the same seller. If you contact the seller before buying you can make shipping arrangements for purchases made through DHGate.
