Crest Whitestrips - where to buy?

[Dulcimena]

Where are people getting them? They used to be on ebay but I'm not sure I trust buying from there any longer. Any other sites that are reliable and trusted?

Amazon.... The USA site, rather than the UK one sells them. Some sellers deliver to the UK.

Thank you!

There's a website called Rose's Beauty Store that sells them

I've just loaded up on the most powerful ones in NY last week. They cost about £55 a box for 20 packets so about £2.75 per strip. Just had a look on eBay and there aren't that many authentic looking Crest ones on there - there used to be loads. I was thinking of selling some myself but looking at the prices - sellers are selling for less than I paid so possibly are buying them wholesale somewhere? or are knockoff
Which doesn't help you much OP but I would try and find a US seller that will ship to the UK. And thanks Mitzy for the tip - I'll have a look there too!
