I'm posting this for other military / veterans / retirees who qualify with the VA system and are interested in ARB equipment.
There's a site
Discounts for Veterans, VA employees and their families! | Veterans Canteen Service that specializes in online sales to vets for a wide range of products. (It is related/operated by govx.com.) As with any on-line shopping, some prices are good, and some are higher than elsewhere. Some like the site, some don't... remember, YMMV.
You have to go through the fairly standard process for validating your military service, but as I recall it was fairly quick.
I was in the market for an ARB compressor, and their price with shipping was comparable to other on-line sources. However, they weren't charging sales tax for Arizona, so buying from them was on my short-list. I hadn't pulled the trigger on that purchase yet...
Good thing, because they just announced a 15% off sale (code 15OFF4VETS at checkout) good through midnight on 30 April 2020. "Exclusions apply," but I just ordered a compressor, and sure enough it qualified for the sale price.
The site has lots of other products as well, but since it is rare to see this kind of deal on ARB products, I thought it worth a special mention. They sell the twin, single, and locker compressors. They also sell a number of the fridges and the fridge slider.
I'm sure there's also other good deals to be had on their site with this discount. Hope this proves useful to someone.
(I guess this web site doesn't properly encode the greater than or percent symbols when used in the title...)
