The United States Postal Service's stamp price increase will go into effect on Sunday, July 13. Here's how much they'll cost.

The postal service said the "price adjustments are needed to achieve the financial stability sought by the organization's Delivering for America 10-year plan."

American consumers could see a price hike and some restaurant owners may face shutting down, as a nearly three-decade-old US-Mexico trade agreement may give way to 20.9% tariffs on most Mexican tomato imports on July 14.

A 17% import tax has been slapped on most fresh Mexican tomatoes. Proponents of the tariffs say it’ll help rebuild the shrinking tomato industry in the United States, but experts say prices will go up as much as 10% at the store in the meantime.
