Just a heads up:
I ordered a gasket and seals from BMA and they were going to charge me $12.50 to ship the .79lb package UPS ground! This was over 40% of my total order cost. Anyways, after talking to a rep, the site tends to over-average the shipping costs and they refund the difference. In this case, she said it was an oversight and refunded $8. If shipping seems outrageous, definitely contact them for a refund. They were nice enough about it and took care of it right away, just make sure to check your order after it's processed.
