I am assuming (instert standard joke here) that all or alot us experience this. Sales growth is up year over year, however there are just weeks year after year with almost identical sales lower than yearly avg. with absolutely no apperant reason. I am having one right now and it drives me crazy! Average weekly sales are 8300-8500 this particular week of every year (6020, 6123, 6600, 6400, 6220) pretty sure not weather issue. Just can not put my finger on it. advertising is consistent. Does anyone else have similar weeks of the year, and more importantly have you been able to identify a causal relationship?
