Interesting - why do you say it would be nice if the posted stated that it was an affiliate link? Do you feel it takes away an option from you or reduces the link's value?

It reduces the link value to me since now the poster is financially motivated to post it. So do I trust that it really is a good product or is the poster just posting an affiliate link so that they can earn money or is it somewhere in-between.

You appear to be linking to heat shrink tubing for the printer, rather than the printer itself.
