About 4 years ago, I bought 3 syringes of tooth whitener from my dentist in Cork for EUR300. At the time I took a very sharp intake of breath at the price but figured to get a professional strength product, I would be obliged to buy from a dentist.
How wrong I was!
My sister found the same product on a U.S. website last week for about USD55 for 6 syringes but they don't deliver outside US.
I eventually bought 6 syringes on a UK website a couple of days ago for GBP42.63, including postage.
What a mug I was.
