Bottle fill price does vary depending on where you exchange, If i exchange my bottle here at the local farm store it is approx $51.00 w/sales tax for a 122 cu ft argon. If i drive 38 miles to North Kansas City it is $28.80 w/tax

Bottle price does vary by location adn also supplier. I currently get my gas from Matheson Tri-gas and pay $30 for a 330 cf bottle. I was paying close to $50 when I was getting it from Airgas.
