(NEXSTAR) – Paris has long been considered the fashion capital of the world, but even people uninterested in haute couture are likely to do some shopping when visiting the city. Whether you’re looking for souvenirs, a new outfit, or some snacks to bring back home, cluing into French shopping culture and norms can help you navigate the boutiques and department stores – and help you save some money.

Read prices correctly

The French have actually made this part of shopping easier for you than we’re used to back in the States. Sales tax is already included in the listed price on tags, so what you see is what you get. That means if a t-shirt is listed as being 30 euros, you’ll actually pay 30 euros exactly at the cash register.

The same goes for groceries and menu prices at restaurants – no sneaky surcharges that catch you off guard.

You actually might be able to opt out of taxes

Speaking of sales tax, you might be somewhat off the hook when shopping as a tourist abroad. When making larger purchases, you may be eligible to get the VAT (value-added tax) refunded to you – and it can be a pretty sizable discount.

Here’s what you need to know: Any time you’re spending more than 100 euros in a single store (in one purchase or over the course of three days or fewer), you can ask the sales clerk for “détaxe” forms. You’ll show your passport and they’ll do the rest. Just keep those papers and your receipt, get to the airport early, and use the automated kiosks to get your refund.

Doing a little bit of extra work can save you about 20% on your shopping spree.

Don’t forget the golden rule

To blend in with the locals – or at least not stand out as an obnoxious tourist – there’s a golden phrase you’ll need to remember. The good news is it’s simple: “Bonjour.”

It’s customary to greet shopkeepers, sales clerks, bakers, servers (and so on) when you enter a business in France. In fact, not doing so can make you come off as rude.

All it takes is a simple “bonjour” (hello) or “bonsoir” (good evening) to start your shopping trip on the right foot.
