SERVICE IS GOOD.. While I understand availability can be tricky, resulting in a price increase, you've never been out of stock , and the price has increased. this wouldn;t bother me otherwise but.. you're the only company that sells the higher range strips. i have spent hours looking online looking for another supplier. i feel your pricing reflects the monopoly you seem to hold. i'd like to get better pricing as a we purchase them for resale. i've also ordered from you guys for 7-8 years.. i know our volume is minimal, but that's mainly because we don;t have a pile of peroxide clients. thanks

Not sure who you are comparing us to but the only "monopoly" we have is on the best prices for 5 or more & a 3 year guaranteed shelf life.  Actually, we've held prices from Jan. 2019 till end of 2021 and, as you noted, we are never out of stock!

Product arrived in a timely fashion and was just what I expected, at a great price.

If you are using 1 strip per week, you can actually save a little bit buying 2 at a time.

Our discounts start at just 2! And it costs the same to ship 2 as 1.
