Source for plastic wire for bending

[Faddenator]

Does anyone have an online source for that green plastic coated wire used to bend plants? I use a lot and it's pricey from Walmart at 50 feet at a time. I want a large spool. Any tips? Ideas? Sources?
Many thanks,

I've always used BURPEE brand sturdy plant ties. It's 3 dollars for 100 feet at Home Depot... or any garden store most likely. Not sure where to get industrial size spools.
