I'm not.
I find most of the big "Sale" periods these days are just a big marketing gimmick, either prices are hiked up before being reduced, or what's available is stuff I don't want anyway. Desirable products don't tend to be reduced below a certain floor.
I monitor prices year round and I do find there are a few quiet troughs when you can pick up a good deal - winter coats in early summer etc, but few retailers truly discount now, you are often only getting lucky with an odd size left available.
The real key is to try and ignore all the marketing and only buy what you actually planned and really want or need.
