I wasn't trying to be harsh. A refund is exactly what OP got. By her comments, she wrote that she does not have a
Coach boutique in her state, hence she was working directly with JAX and with a supervisor as well. Coach has free shipping & returns in the States, right? So if after 5 replacements (and shipping both ways, on Coach's dime; complimentary gift packaging if OP requested it too) the supervisor can see that OP will not be happy with the quality of the bag, and can no longer keep sending bags to her that she will have a high likelihood of rejecting.
It's not Coach's fault, there are many people who are happy with their bags, plus as leather is a NATURAL material it will have natural variations and five times should be enough to pick one. If OP expects that she will have unlimited replacements (or even that she is entitled to a discount for a future purchase - why?) then Coach is not the company for her.
TPFers in the other forums have moved away from LV because of declining quality control, away from YSL because of declining leather quality, etc etc
It's completely up to you what you are willing to accept in a brand. OP isn't wrong to want what she wants, she just can't have it from Coach, and shouldn't be upset when Coach is telling her that they can't live up to her standards.
