Thanks for all replies. I found an internet coupon for free S/H on the Masterbuilts, if the coupon code works, I may go that way.
Today I was grilling some chicken breasts and ran out of gas. The breasts were just about done so kept the lid closed, took the empty for a trade-in at the local convenient/corner store for an exchange, stood in line (4-5 people in front of me) & got to the counter; they tried scanning in the code and put the wrong one in ($53.99.)
Then they rescanned the correct code and it came out to almost $25 with tax. I was in a hurry to get back grillin so said OK.
Anyway, they couldn't find the KEY to the Blue Rhino cage! So after almost 15 minutes, I went somewhere else. It was $21.74 exchange at the 2nd place.
This has just dulled my liking for propane. The only thing keeping gas in the competition is that the Walmart nearby has a GOSM for $100 + tax. If they gave me a "clearance deal" on it I may still bite.
