I'm not sure if many hams are aware that if you sign up with Amazon.com's Smile program ( https://smile.amazon.com/gp/chpf/pd/ref=smi_ge2_uaas_lpd_upd ), but Amazon donates 0.5% of the price of eligible AmazonSmile purchases to the charitable organization of your choice, including amateur radio clubs. (I signed up to donate to the Dallas ARC.) Check out the provided link to see how your ARC can register.
