Is pharmaca.com Safe?

Does not honor sale prices. I ordered product on sale and the item was cancelled. I called and was told it was not cancelled that it was on backorder. I patiently waited over month and then was told and the website said it was complete. I never received product. I tried to contact them numerous times and was not successful. I finally was able to get ahold of someone. I requested the same product but instead of the original 120 pills (that were not in stock) that they send me two (60 pills) of the exact same product. That request was denied. All that I asked was for them to honor the sale price that they offered. I had also ordered the exact same products a week earlier and I asked that they refund the difference in the non sale price. They refused and I was told that the items that I purchased were not supposed to be on sale. So if their company makes a mistake they will not honor sale prices or provide an type of remedy. Now all the sales are over and they couldn't even care.
