I decided to do affiliate marketing on my A/C website. what do you think is the best product or service I can promote? most of our customers need between $1000-$5000 to replace their units. i was thinking about home equity loans. 100% of our customers are home owners. they all are in Housotn and surrounding areas. they usually have good credit with a few exception. i get around 3000 unique a month. thanks in advance for your time.
