I bought a 1.5 CT Princess Cut engagement ring from Groupon and boy was it horrible. I paid $1,200 with a MSRP of $11k. Was so excited waiting for it but as soon as I opened the box, my heart sunk into my gut. I couldn't ask my girlfriend to marry me with this ring. I took it to multiple jewelers and none of them would buy it from me. Not even for $500! I tried to get a refund but they had a no refund policy. I will not buy anything from Groupon again!
