Try Amazon for this 'problem'. Sometime ago someone on this board referenced head lamps that had magnifiers. She said it was a helpful device for her quilting and added a link to Amazon. I clicked the link and looked at the device. The very next day ads for that device and similar ones popped up on my Kindle Fire every time I opened it. Coincidence? Don't think so! I am not sure what I think of all this intrusion; I don't like it, but, shopping the old fashioned was has become increasingly difficult.
