No such foreigner price in Japan as business custom in daily life.
If so 本体価格(honn-tai ka-kaku) is base price(= without sales tax)
but also in Japan any customers must pay "sales tax" 8% plus(x1.08)
for any daily life shopping together (already answered by above posters)
税込/税込み(zei-komi/include sales tax) price is so.
"税(zei)" means just "tax" using for any kinds diffrerent rate very widely.
But price label's 税 means short of 消費税(shou-hi-zei/sales tax).
https://en.wikipedia.org/wiki/Value-added_tax(wiki using another word "consumption tax")
If written 税抜/税抜き(zei-nuki) means "without tax"
but need sales tax 8% plus when paying same.
価格(ka-kaku) means just "price".
本体(hon-tai) means "base/original body" but this body means just "product".
If label prices are not matched 8% tell us written price both also what product bought.
Especially conveni foods/drinks price down
also discount campain frequently for increase sales numbers usual.
This is 50円引(-Yen biki/off) product label.

A lot of written include sales tax price larger exist
http://img03.ti-da.net/usr/s/h/o/shopisland/IMG_6475.JPGbut base price make larger means just "cheap!" appeal/showcasing when first look.
If found only single price(without notes/explaining) means include sales tax no worry.
Single price (not only as label) also usual train/bus/taxi fare,restaurant menu and more.

: Kore-wa zei-komi(kakaku) desuka?/Is this (price) sales tax include?
