MIAMI -

Retailers in Florida will not be charging sales tax to buyers of school supplies, clothing and electronics related to education beginning Friday.

Purchases done over the Internet during the three days were included, but the rules that applied at stores also applied on the web.

Shoppers must beware of some legal limitations to the discount. For instance, items sold at the airport are not included.

"Fla's Sales Tax Holiday runs Aug. 1-3, 2014 for new school year," Miami-Dade County Superintendent Alberto Carvalho tweeted Tuesday.

Miami-Dade students are set to be back Carvalho also shared a link to a back-to-school kit for parents.

Keep in mind that not all of the rules make sense. Some of the items that are not exempt from the tax include books, white paper, liquid correctors, masking tape, staplers and staples.

The rule applies to items of clothing and footwear worth less than $100 per item. School supplies must be less than $15 per item.

The first $750 of the value of computers and related accessories will not be taxed. The law excludes items "that are not primarily designed" to process data such as video game consoles, cell phones and televisions.
