A marketing ploy I absolutely hate!

This is sort of off topic, but I need to vent.

I get a lot of e-mail from companies with which I've done business. And one of those companies sends me e-mail just about continuously, with coupons offering deals that are good only for a short time. I just got one, which must be used this weekend, for a pretty good deal. But it's this "use it this weekend" thing that bothers me.

Like most people, my income comes in discrete chunks. When I was employed, it was usually every two weeks; now that I'm retired, it's monthly. (When I was employed, the frequency varied with the company; one paid me weekly, one went from monthly to semimonthly just after I started. But biweekly was usual.) So every month, there may be a period when I'm particularly short of cash, and if I get a good deal like that, I'd like to put it off until I get my monthly deposit. (Other months, I've spent less than my income, so I may have more to spend at this time. Only a few of my expenses, like the rent, are predictable.) This is one of those months when my expenses fit my income pretty closely. But I get paid next week. So I don't want an extra expense this weekend.

It's these short-term deals that really get to me. If I knew I was getting another coupon soon that was equally good, I'd simply pass on this one. But they send different coupons in different weeks. Some are only good on things I never would buy even if they were free. This is a marketing ploy, I know. But it hurts. If the coupons were good for more than just a few days, I'd use the ones I wanted to, but when I had the money. This time, I'm forced to choose: do I pass on this coupon, or do I dig into savings (and hopefully remember to replenish after I get paid)?
