Two of the companies that I get products from have given me discount codes to share with friends to gain market exposure.
Ardent fishing reels and rods, 25% off your order from their site (https://www.ardentoutdoors.com/): TQ252017 (must use all capital letters at checkout where it says coupon code).
Interstate Bait (Sunflower Seeds), 20% off your order from their site (https://www.interstatebait.com/): freidigc16
Feel free to use them or share them with people as much as you want. Let me know if you have any questions about products or how to use the code.
