I am fine with five-day delivery service, but I would prefer they drop Wednesday instead of Saturday.
Monday: No mail
Tuesday: No mail
Wednesday: A ton of mail.
Thursday: No mail
Friday: No mail
Saturday: A ton of mail.
Actual days and quantities may vary, but the pattern is fairly stable.
We do rely on the mail quite a bit. I agree with you; I think Wednesday would be the best day to cut. The problem with Saturdays is that, when they have the many federal holiday Mondays already as no-mail days, it can get dicey for delivery and turnaround times if they skip 3 days in a row very often.
