The scourge of Winter Storm Uri is a brutal reminder for Houstonians to be prepared for the most extreme weather — and subsequent power outages. (Houston, as CultureMap reported, bore the worst of the storm.)

To that end, a major tax break will help locals do just that.

Those who purchase emergency supplies can enjoy no sales tax on those items, per the Texas Comptroller’s Office. The sales tax exemptions run from 12:01 am Saturday, April 24 through midnight on Monday, April 26.

Shoppers who aren’t looking forward to braving long lines are in luck: products bought online, by phone, mail, or custom order also qualify for the exemption, per a comptroller’s office statement.

Here is a breakdown of equipment and supplies eligible for the tax break, per the office:

Less than $3000

• Portable generators

Less than $300

• Emergency ladders
• Hurricane shutters

Less than $75

• Axes
• Batteries, single or multipack (AAA cell, AA cell, C cell, D cell, 6 volt or 9 volt)
• Can openers — nonelectric

• Coolers and ice chests for food storage – nonelectric
