Query: Buyer Beware of Return Policy If Wrong Size

I was carefully measured and ordered the large. But on my side it is too high. I did not break the sealed plastic envelope and so it is still new and can be resold as such. But unless an exchange pillow costs the same or more -- and guess what, the next size down is less expensive -- there is a 20% restocking charge in addition to the (understandable) shipping cost to me and back to the supplier. That is a lot of money for getting nothing ! I am an Amazon Prime customer so I don't like having to pay shipping for third party purchases (where AMZ does not do the fulfillment) but that is out front. However, you would have had to check out specially this sellers return policy to know you may get snookered. Best read some of the other negative reviews here too for quality of service problems if not the pillow itself. And if you purchase and you are in doubt of which size to order > order the smaller just in case.
