Personally I think the coupon program is a scam.
I ordered two coupons for myself and two for an elderly friend to be sent directly to him in an adjacent town and none were ever received.

Last month I ordered more to be sent to my father home and to my brother’s home and they too have also never been received.

When inquiring about the status, the first two sets they say have expired and the second two sets they say were sent.

Out of four orders to different locations, Zero was received.
That’s a scam.
