Yeah honestly peeling off stickers at the boutique sounds good to me.
I think the "go the reseller route" response comes from a swath of comments on this forum from new frustrated clients who are asking about their odds of getting a xyz bag. As we all know bag offers just depend on so many factors and there is no known formula so if someone is in search of a bag with specific specs it would be easiest and more economical to go the reseller route. I personally do not support resellers and would only buy vintage bags in the future, but this is just the reality of things right now.
Trust me I understand your frustration. I speak multiple languages so I've been getting some culture specific instagrammers being recommended to me on my feed. They upload picture of themselves shopping, filming bag offers and getting VIP treatment at the boutiques but if you read the comments (not in English) they talk about this bag being up for sale, how one might go about purchasing it etc. Its baffling to me how the SAs at the boutiques don't suspect this, or perhaps they just turn a blind eye. I've also seen some instagrammers who sell everything at massively inflated prices just because the demand is so high in their home country. They literally recruit "buyers" who essentially act as personal shoppers. I've even seen a case of an instagrammers who runs a "buying school," aka teaching other people how to run their own personal shoppers business, including how to smuggle these goods back into their home country without paying customs, how to redo the packaging etc. It's absolutely insane.
