Based on the anecdotal evidence just on this thread, it's clear that receiving PCEs is not based solely on your buying history at FP stores. It is also based on other info metrics based on other purchase patterns outside
Coach that Coach buys from other websites/data mining companies. I would say yes, Coach absolutely (thinks they) knows your age, the websites/companies you buy from, and maybe even your google searches from the past few years. All of that information is out there. Do not underestimate the amount of information we as consumers leave for Google,
Amazon, Coach,
Nordstrom, etc. to sell to outside companies.
That said, I am a huge online shopper and frequent FP shopper. I have received every single PCE in the past 4 years. And I am definitely not in my 20s.
