Those are 'spensive, guys!
The funky thing about the AB Sungrown is that its MSRP is only $5-6 (I get them at the B&M for $5.50, and it ain't a cheap B&M) and I can never find any discount online. One of the few I've seen where they don't inflate the MSRP and then discount them to make you think you're getting a "deal."
