They do NOT put it in BOLD print that the rebate has to strictly be used at Menards. It is hidden in small print, even on their flyers.
I just sent them this email: We have spent a lot of money over the years at Menards, but I do have a complaint. If you are going to give the customer a true "rebate", why not give them one that can be used anywhere, including your stores instead of giving a "rebate" that must be used exclusively in your stores for your merchandise? Why not give the customer the option of freely using their rebate at your establishments, or if they choose to use their hard earned dollars at another establishment, possibly for a totally unrelated purchase? This would certainly generate a lot more good will and possibly more return customers. Making a customer use their "rebate" at your discretion really isn't a true "rebate". I know it would surely make a difference to where I shop.
Rebate=A deduction from an amount to be paid; an abatement; The RETURN of part of an amount already paid.
