Well I sent the tank via FedEx ground from Oklahoma to California on 7 Aug, they shipped it back to me today. The cost to date is 16 dollars to ship it to them, we included a shipping document back to my in-laws house which cost 17 dollars. Inca charged us 45 dollars to weld the cracks and test that tank plus it cost me 10 dollars in cardboard sheets to make a box for it. The total cost, provided nothing happens is 88 dollars.
I would like to have just replaced the tank with a new one and would have paid the slightly less than 300 dollar price tag for it but the additional 160 dollar shipping fee the other vendor wanted was simply outrageous especially since they are in essence in the same area as Inca is. I guess if it were the only option I would have had no choice but by inquiring here and doing some leg work I have saved over 350 dollars
. Thanks to ever one's comments and this great forum. Thank again and again.....
