Know-How Exchange : Copywriting

We're in the seasonings business (spices, sea salts, etc.), and our holiday show season is starting this weekend. These are retail shows but once in a while you get wholesale business too.

For our booth this year, I'd like to make signs that convey two messages:

1. it's cheaper to cook at home in this economy, so buy our products
2. we have several elegant gift sets under $50 (we have 3 for $35, 1 for $50, and they can customize anything they want which usually costs $35-40).

I'm struggling with coming up with wording for these. They have to:

1. Be short, like 1 phrase long (not even a full sentence)
2. Sound upscale to match our product lines
3. Be visible and catchy to bring someone in that just happens to be passing.

We will be printing black & white posters, around 18x24" each (or are open to other size suggestions). No graphics, just large text (any suggestions on all caps/initial caps, font, size?).

Of course I'd be very happy for any additional booth advice as well, and don't be afraid to tell me my approach is totally off!

Thanks,

Kit
