I've never shopped around but I always order mine from Mossy Oak Nativ Nurseries. If you get the Tree Protector Package and order 50+ you get them for $4.75 a piece (that's the tube, fiberglass stake, and zip ties). Shipping is included in that price. There may be better deals out there but I've never looked. Some of these tubes I'm using from Nativ are 6-7 years old and still going strong.
