Kenny, check out this free discount card from GoodRX. I have a prescription that costs $150/month and am now paying $27/month for it simply by having presented the card to my pharmacy. Incidentally, it was a pharmacist there who mentioned it to me, prefacing his suggestion with "I'm not supposed to tell you this, but." So, you can keep your money in our economy.
It's technically illegal to ship/bring rx drugs across the border (into the US), if busted at customs you could be in a lot of trouble! There is apparently an amount you won't get dinged for, I think less than 3m supply, but that is still up to the agents discretion.
No idea on which sites are safe or not, but you'll save a fortune if the drug is cheaper here - the exchange rate is very USD favourable right now.
