ERLH, thats what they charge in KW HD, its a deposit,,as far as 200 i bet they wouldn't. you have to turn them in person, thats why you should re read my post. as far as $30.00 tanks go after $29.95 in shipping,,,,do the math,,,,or if you drive down here to try and profit off a few tanks,,don't forget gas here is between .50 and .75 more per gallon go for it,,,,to give you some idea about things costing more,,I've bought books off of amazon for .10 and $3.95 shipping,but to answer your orig. Q: if you want a 20lb propane tank and don't have one to exchange you pay a $40.00 deposit plus the cost of the propane $17.95 for 15 lbs,,at the last time i checked. i don't make the rules. just live by them.
