We hear about merchants to avoid (Sergio Pilati Muebles) but DEVLYN did a super, over and above the call of duty job for me and I want to acknowledge it. They sell prescription glasses and high end sunglasses. Their stores in some of the malls are easy to spot with the green letters of their signs. I simply am overwhelmed by what they did. I bought a pair of Coach sunglasses as a gift for my bff. She soon noticed a hairline crack on the part that came aross her nose. DEVLYN graciously exchanged them for another pair, although the tint was a bit different. I gave her the other pair and when she took them out of the box they had the same kind of crack that the first pair had. I did not even think to inspect them at the store. This pair never even went on her head. We went back again the next day and DEVLYN suggested we pick out another pair. She looked all over the store and I insisted that we find something that we both liked. Well, don't you know what we both liked the most was a pair of Dolce & Gabanas. I swallowed hard and said they were perfect. She offered to pay the difference, but I said it was my gift but it was now her next year's birthday present as well. I asked what the price difference was although I already knew it. They spoke among themselves for a minute or two and finally said NADA. I mean the Coach's were not cheap but the D&G's were deadly. I have never heard of such a thing in Cancun, let alone have it happen to me. Now, every time I walk by the store I always look for these two wonderful ladies and wave or walk in to say "hola". DEVLYN IS NUMERO UNO IN MY BOOK.
