Rock Auto and Canada shipping

I ordered rear brake drums for 72 demon the 1 3/4 type hard to find $85.58 for both total weight 27.15 lbs $46.10 shipping no extra fees. I ordered these locally 3 times and they were never right 2 1/2 was what showed up. the person I dealt with tried to have warehouse measure them to make sure of size to no avail so he told me he would split shipping if I had to return them. They were correct and they only had 8 sets left and they are no long being made if anyone needs them.
