I certainly don't mind your sending my posts to anybody you think can help.
That's more likely than all these vendors using the same provider for the receipt confirmation service.
I don't agree with that.
I think it's altogether likely that many vendors, mass-mailers in particular, are paying for this service to increase their reach while possibly reducing their
outreach costs, and I don't think they'd be the least bit pleased to know that their front-man is alienating, rather than encouraging potential customers.
I haven't searched, but from what's been posted here I infer that there's a good deal of consternation over these "receipts".
I stand by contacting the retailers and letting them know that you don't like it.
