I ordered a bunch of DVD-Rs and cases from Meritline a while back and it's time to order some more cases (found cheap DVD-Rs in B&Ms). Now I don't remember the shipping cost being so high from the first time around. For 150 of these cases, it's going to be $20 for shipping. In the long run, that still averages out to 50 cents per case, much better than in B&Ms, but it hurts to see that the shipping costs almost half that of the product cost. Any suggestions?
