If I owned a restaurant or bar, I would have a 10 cent wings night, where
we served buffalo wings for ten cents a piece. That's super
inexpensive, because normally, you'll pay something like $7 to $9 for a
plate of maybe six wings. But why would I do it? Because I'd want you to
buy the beer, which is an even higher markup.
What is your plate of 10-cent wings?
I bet if you looked closely at what you are doing you already have something that qualifies. It could be a:
a giveaway contest
a tutorial on your blog
What is your upsell?
Don't forget about this part! If you take a loss on one item, you've got to have a plan in place to come out ahead on the upsell.
Are you using your wings to get email addresses so customers get repeated exposure to you and your products? Emails are best, but Facebook likes, tweets, Pinterest re-pins...these are good too.
You can also go for product upsells by selling coordinating items with higher profit margins. For example a jeweler might offer a discount on earrings (the wings) when someone purchases a necklace (the beer). An artist could sell a low-cost calendar and get 12 months of exposure. A simple nudge, like a discount on a larger print, will drive in sales.
If you try something and it doesn't convert to the upsell or increased exposure - then change tactics and try something else. Don't be afraid to experiment until you find what works for you and your audience.
The last thing you want to do is to break your back for the cheapskates that order the wings and a glass of water.
