i think they wouldn't have to change the ads, if people see the ads they would know that's the price without tax (it's not as if they don't already have the problem even with taxless price tags) but instead of never telling the customers how much they really have to pay until they stand at the check-out they could get the information when they see the product on the shelf. that's much better for people who are just on a shoppig tour which should be a much higher percentage as people who want to buy something they saw in an ad  and it's especially much better for people who come from another city/state/country with another tax and want to buy something.

give the customer the price he has to pay and when he pays for it he will get a receipt with all informations about how much of the price is tax and everything and not "give the customer the price without tax and he will know what he has to pay when he already has his credit card in his hands"^^

but if tax really changes every few months and not only once every few years this could be really a reason because that would be too much stciker prices too change all the time.

So you're saying it's OK to advertise the untaxed price but the sticker price at the store needs to already have the tax price included?

Sounds to me like that would confuse the hell out of people.  "I saw the price for $100 in the newspaper so why does it say $107 on the box?"

And our recepts do show a full breakdown of the taxes.  Like I said, most people are already well accustomed to calculatig the tax in their head.   They know it says $100 they'll likely pay $107.   If it's $200, they'll likely pay $214.

I think they don't put the taxed price on the stickers so as not to confuse people from the advertised price.

Exactly, since taxes vary from state to state and even county to county, saying it will cost, "$207" may not even be true. To keep the confusion down, the compaines use a set price and allow each state to apply tax to the MSRP (manufacture suggested retail price) of the product. This keeps the manufacturer from being liable when they state a price and it applies in one state but not another state. Saying $199.99 suggests that is what the manufacturer is selling thee item at, and the state/county/whatever will apply THEIR taxes to the product.

but it's less confusion to see the price on the sticker and have to pay another price when they have their credit card in their hands 30 seconds later? both would confuse people if you really think that could confuse them but one would be much fairer because people who are not from there simply don't know the tax and don't have that calculation in their head like people who live there and there are also people who are not even able to calculate the most simple math so it would be also much better and fairer for them.

Perhaps had they started the system that way in the beginning, it would make sense.

Trying to it change it now would be disastrous.

like i said to viper, if you know that ads are without tax there is only as much confusion for you as if you see it on a price tag without and have to pay then a price you don't really know before (even if you know your tax most want really know the exact price not to talk about everyone who doesn#t live there and will buy something there)

no clue why ow both of you think people wouldn't understand that price tags have tax included but ads not but they understand that price tags have no tax included but they guy on the check.out tells you another price with tax then...

Tell that to my daughter, Iyolah. She died before ever paying a single tax dollar.

wow...and the 3DS isn't $170, the PSV isn't $299, and the X360 and PS3 isn't $299 either.  C'mon only 2 things sure in life are death and taxes!
