If you've snagged an invite to Thanksgiving, make sure you're not showing up empty handed. Even though you are not cooking the main dish, there is no reason you can't contribute.

Consumer expert Caleb Silver says prices are manageable this year if you plan on bringing a side or a pie.

According to Silver, the side dishes tend to be the cheapest parts of the meal and many of the items you buy can go a long way in more than one dish.

If you're designated a dessert, Silver says pies are a relatively small slice of the spending.

"Those are the only cost around $6 at your local grocery store," said Silver. "Though, you can get ones that are much more expensive than that"

If dessert is already assigned, drinks are another option.

"If you're thinking about bringing wine or refreshments, a bottle of wine is averaging around $14 a bottle," said Silver.

Looking at the overall trend, Silver says adult beverages should not bust your budget.

"Alcohol prices, especially for wine and spirits, are pretty flat from last year. They've come down in price over the past couple of years. They're still up about 20% over the past four years, but prices are leveling off."

If the money just isn't there this year, offering to clean up is a free way to be a great guest and a helpful way to secure your spot for next year.
