In many countries the price you see is the price you pay. In the US, the number in the ad is often the lowest possible number. Learning the words helps you see the real price.
Why the register price is higher
Sales tax is added at the register in most states. See Why the price changes at the register: tax and tips.
Tips are expected in many services.
Some cities add bag fees or bottle deposits.
$9.99: almost $10. Prices ending in .99 are made to look smaller.
"Starting at" / "from": the cheapest version. Bigger sizes, better seats or more data cost more.
"Plus tax" / "+ fees": the number does not include them.
"Per month" for phones and cars may hide a long contract or financing.
MSRP: the maker's suggested price. Stores often sell for less, and car dealers sometimes for more.
BOGO: "buy one, get one free". "2 for $5" often means each one costs $2.50 even if you buy one. Read the small print.
"Was $50, now $30": check if the "was" price was ever real.
Unit price: the small number on grocery shelf tags showing price per ounce or per count. Use it to compare sizes.
Member price: the lower price is only for people in the store's free loyalty program.
"Free trial": becomes a paid subscription unless you cancel. See Free trials, subscriptions and auto-renewal.
Service, convenience or processing fees on tickets, food delivery and online payments.
Resort or destination fees at hotels, charged per night.
Card surcharges: some places add a small percent when you pay by credit card. Signs must usually say so.
Activation, installation or equipment fees for phone and internet plans.
Admin, amenity or application fees for apartments.
Since May 12, 2025, an FTC rule requires businesses selling live-event tickets and short-term lodging (hotels, vacation rentals) to show the total price, including mandatory fees, up front. Other businesses are not covered by that rule, and some states have their own fee laws.
How to find the real price
Go to the last checkout screen before you enter card details, and read the total.
Ask in shops: "What is the total with tax?"
For services, ask: "Are there any other fees?" and get the answer in writing or email.
Compare the total, not the advertised number.
At checkout, stores often offer a protection plan for electronics and appliances. It is optional. Many products already come with a maker's warranty, and some credit cards extend it.
Comparing two hotels by the nightly rate when one adds a large resort fee.
Thinking "2 for $5" requires buying two.
Paying for an extended warranty without checking what it adds.
