Button-Up Cropped Knit Cardigan

I'm usually a size small when it comes to clothing. However this cardigan runs large on the sleeves, which were abnormally too long to be a size small. They exceed my entire arm and hands. I've also noticed a few loose strings/yarn hanging from the back of the cardigan. Too bad Nordstrom rack doesn't offer exchanges or free in-store pickup to local stores. On Nordstrom rack's part of customer service, they seem to be going downhill to require an unreasonable minimum spending amount to get you "free shipping". On my recent order (last Wednesday) I only had to spend half the current minimum to qualify for free shipping. Alternatively, they ask you to pay $10 extra to pack and ship your order in a ridiculously huge box. There are more sustainable and cost-effective shipping methods, do better Nordstrom! I will definitely be returning this item and ending my patronage.
