"$2.50 to mail one chip"
I dont wish to sound contradictory, but, Ive just got your latest rate charts and they show the rate to the US as $1.86CA for up to 100g (That will get you up to 8 chips in a padded envelope)
If you were to send them airmail letter post (which I wouldnt advise) it would only be $1.10CA for up to 50g (4 chips)
What am I missing??

BTW, you need to contact a guy called Barry H. He is President of the roulette harvesters association

Barry, I forgot to tell you I beat my record at the Empire a couple of weeks ago. 24 stacks. 3 more than I had when I got caught by the HR
