If I bought every high-end designer piece that I kind of liked and purchased mostly because I could have it at a deep discount, my closet would be full of stuff that I never wear. (I dealt with this for a few years and wasted tons of money before I finally wised up and decided to change my perspective) These days, I try to be more realistic and practical about my purchases. I have to LOVE it...whether it's cheap or expensive, I won't buy it unless love is involved, LOL.
That said, I would buy a metallic leather jacket only if my leather jacket collection already had the basics, such as black and brown. The images are grainy but the black one does appear to fit you better.
(thithi -- I looove your "sale goggles" term! So very true!)
