Hi Anthony, YES, there are affiliate programs for plumbing and heating. Faucet.com and HomeDepot both have affiliate programs that you can join and earn a commission. Now, obviously, if customers need very specific parts only, this may be an issue. But, I know marketers that make a nice income using sites like the ones I mentioned and others. I would front it with your own website and build a following. These are things discussed within the Wealthy Affiliate program, how to build a website and earn money in something you’re passionate about. Check out Wealthy Affiliate. It’s free to join and I’ll be happy to discuss this with you more within the membership website.
Many voucher code web sites use a click-to-reveal format, which requires the web site user to click to reveal the voucher code. The action of clicking places the cookie on the website visitor's computer.
