The Hidden Forest

Here is a little puzzle for you

3 goblins, who happened to be very good at alchemy, made a great many number of poison and antidote potions, and brought them to big city to sell.
They rented a place on the local bazaar, and put up 2 vendor signs - one for Poisons, another for Antidotes.
Unfortunately for them, the business was going very slowly - no one wanted to buy from goblins.
Then goblins decided to be tricky. They crossed out one of the signs, and wrote two words over it... By the end of the day they have made a great deal of profit.

Question: what did the Goblins do?

PS. If you know/figured answer right away, don't post it right a way - give others at least 24 hours to figure it out (you may make a post saying that you THINK you know the answer, and feel free to discuss it )

frist goblin kept his sign saying Poisons...second goblin crossed his out and wrote No antidote and prob pushed htem togeather so it read "Poison No antidote"

i am curious what effect it would create then to improve sales? =)

Poison with no antidote? Rogues would like that

husbands to kill their wifes..bosses...lots of things with threats like that

its a curious approach, but no, this is not what they wrote

Illusion goblin + Antidote! =p

I'm thinking "Love Potions" would attract many fools that would overlook the fact that goblins were unlikely to actually make such a brew.....and the victims of their amorous intentions would be very interested in the "Antidote", and desperate enough to overlook the peculiarities of certain merchants!

The goblin crossed Poison and wrote "(Antidote) And Snuggies"

Everyone went nuts... Cultists were walking around with their bare-behinds sticking out.... It was bad.

lets just say that goblins were honest (to a degree) and they did not mislabeled their products
