What am I missing? You said a candle weighs 4-1/2 lbs, and there's 90 of them? As mentioned, that's 400#. That's not going to ship for $60. What the heck kind of candle weighs almost 5# each yet you can fit 20 of them in a large flat rate? That's 90# worth.........I'm confused. Find some free, large boxes (stores, recycling centers, etc) and ship UPS. You should get a hundred-weight discount. USPS will not be cheaper on that kind of weight. Actually, LTL carrier would probably be your best bet, but sounds like you might not have a way to deal with that.
