How come I bought a pair of Sonoma socks that says on the package 10pairs but I opened them up and counted only 9 pairs???

Because someone opened the pack and took a pair or just discarded them on the fixture and the sales associate has not seen them

I would check that out by calling store and question them

Make sure you have the receipt, along with the the packaging with the soxs, and they should give you another pack that is complete.

Thank you I been trying to tell my grandparents that but they say no so ima do it anyway
