NO...When you try to buy 2 or more ,you can see the price still at 5.3$. DX do not amend their bulkrate price.
They give a discount when you enable bulk pricing for 3+ items. It may show as more per unit, but with the discount that's shown in your cart it's actually less. And what are you talking about the price is $5.30? It's clearly $4.98 for 2 of them for a total of $9.96... CHEAPER than YOUR link, just like I said!
