I forgot I had a shipping address in Niagara Falls, NY. I hadn't used it in several years. It's with CBI on Military Road.
There are a little pricey, I think it's about $6US/package. The annual plan is >$100US and they still charge $1.80US/package.
I stumbled on a place called 247parcel, also located in Niagara, NY. Their rate is $3US <35lbs. They are just across the border, I could walk over and back on a nice day. I'm leaning to these guys as they have more flexibility for pickup if you prepay, and they are cheaper.
Have any of the Canadians here used either of these services? Which do you prefer and why?
