Being in Canada I found that most places charged $20/25 shipping for t-molding.
I thought no way that could be the case, I mean it doesnt weigh much.
I found (and use) gameonmolding from eBay. (forgive me as I can't seem to log in to verify seller)
They shipped for about $7/8 at the time and the molding was about $6.
Keep in mind for me, even locally (Toronto Canada) molding was about $0.60FT + 13% HST.
So all in all, to my door, eBay was same price or slightly cheaper, but saved me the time and gas!
Sadly now the seller charges $14 to ship. I did message him asking if rates had gone up with USPS (which I feel is the best shipping), however I got no response. I know the thing on eBay now seems to be making money off the shipping. Guess this was always the case.
Either way the seller now comes in about $4/5 more than my local seller, but again saves me a drive.
