two years ago, I payed here in Israel 250$ for special made Dental Trays and 2 Syringes of whitener.
every year, I pay 50$ for another Syringe.
I checked the online price:
Teeth Whitening Kit 1 HUGE Bleaching Gel 10cc Syringe 2 Dental Trays FREE Shpg
for the next 30 min - it's only 11 bucks
I should have checked this like you

Joy and celebrations,
