How I Thrifted Vintage Pink Prada Sandals for $0

I thrifted my first pair of vintage Prada and spent a total of $0! ??
They were $50 but I got ‘em for free thanks to a 75% sale and the store rewards I’ve been holding on to since lockdown ?? I’ve spotted vintage Prada “out in the wild” many times over the years but they’ve always been worn out pairs that I didn’t really love or felt were worth the thrift splurge. These on the other hand, were IT. Blush pink + flowers+ in my size! Even the cashier was happy for me ?
