Political signs are the 18"x24" corrugated plastic signs that politicians put out on the street corners when they're running for office. Do the same thing, but with your logo and the special you're running. Make it short and sweet and as big a font as you can get it so that people can read the entire message when they're driving past it.
Delivery sales going down, too? My friend, sounds like you've just had some kind of competition come into your town? Papa John's open up a block away or something?
Okay, I've always lived by the philosophy of winning the "marketshare" battle. I'll guess that well over half the people in this forum will disagree with me, but I don't care what the price is. I care about order counts. I figure if they're ordering from me, no matter the price, they're NOT ordering from the competition. Now, of course, I'm not so extreme I'm losing money. I'm still maintaining a $14.00 ticket average and running about a 28% - 30% food cost, but I am extremely active in stealing customers from the competition.
Right now I've got a new store and I'm trying to break into a well-established market (Domino's, Pizza Hut, Little Ceasars have been here for years and they all, believe it or not, average above $15k per week). For me, it's all about marketshare. I KNOW my product is better than the competitions so I'm in the middle of a marketing campaign attracting new customers with VERY competitive price points. I feel if I can just get them to try my pizza I'll hook 'em.
You want to get customers ordering for delivery? Give them a special they CAN'T pass up. Like...
