Walmart find: 14k 4.38g chain for $89

I love yellow gold, and the Walmart posts in here really fascinated me. So, I stopped by my local store to see what they had in stock. This clearance 20” 14k 3.5mm curb chain looked beautiful, and seemed like a steal at $89 (retail $448). The melt value of the gold (4.38g) is around $220, so I think this was a good find.

I’m still very new to this, though, and would appreciate any tips of things I should be aware of as I look for pieces for my collection.
