Department stores are not usually shopped, other than a specific brand inside a store. Same with Sephora.
Shopping luxury stores is more of a hobby than a job. They might pay $30, but usually there is a parking issue (lots of time to find a spot and not reimbursed). It also takes me an additional 30 minutes to "prep" for these assignments. AKA are my nails done, is my make-up perfect, am I wearing the right jewelry, am I wearing something expensive and current? etc. Lots of work looking rich. All of my 1% friends look rich. It's a rare person who would go in an drop $2K for a bag or $30K for a watch that shows up in flip flops and jeans. (Spare me the anecdotal stories please.)
You could string 4-5 of these into a set, but plan on 2 hours to report that mess.
