Input salesmen don't come to your farm to make you money.
Ya reckon? Zero interest always means it's charged on the front end. Or maybe there's a trap built in where if you stumble it hits you like a ton of bricks.
The only credit card I use is for fuel, an Exxon card because I get 10 to 20 cents a gallon off. They just sent me 3 or 4 pages of legal size paper with small print outlining the new terms. I am good to go if I pay on time in full like I have done, but Boy Howdy the costs if you slip up or take a cash advance. In addition to any penalties the interest is 34% going back to day one.
One of my good friends is in the air conditioning business. It is interest free for one year if he installs your HVAC. I hemmed him up on it and he admitted it (interest) was on the front end. And if you don't pay in one year you have problems.
