$230 is not bad for $1000+
If you go across you have to Show them the Recipt and they will for sure charge HST which will be $130 on $1000. Maybe Duty maybe not. I have not been charged Duty yet while crossing the border but HST everytime.
so $230 - $130 leave you with $100 Saving.
So about $40 in Fuel from Toronto and Back and $5-$10 in Storage Fee's and $3.50 to cross back into Canada... Really worth the drive to save $45?
