I've been burned too many times buying things other than groceries from Wally World. As far as filters, if you've had no problems then I would keep getting them there. Just saying, I know how Walmart squeezes major manufactures ( Levis, General Electric etc) into putting their names on products that aren't up to standards so I am always hesitant to buy from them but I guess that's another topic for another forum lol...hope all is well, ride safe!
