"Diet is now included in that," said Shel Klein, Klein's Supermarket. "The only thing you can get away with not paying tax on is water."
But there are some other exceptions including certain milk and juice products. But Shel Klein is right, diet soda will now be taxed an additional $2.11 per 12-pack if the soda tax becomes law.
And that, his brother says, will have negative effect on city stores like theirs.
"People with the economic means with a car are saying, 'the heck with it,' and we're going to chase them out of the city," said Ken Klein, Klein's Supermarket. "Not to move out of the city, but to shop out of the city."
The other surprise to many Wednesday night was millions raised by the proposed tax will go not just to kid-based programs, but to the city's general fund balance, which has been shrinking.
"I don't think any of us are against fortifying the fund balance," said Bill Greenlee (D- Philadelphia City Council). "It's just we were never told that was part of this soda package."
If passed, the controversial soda package will raise about $409 million over five years.
How will it be spent?
The Kenny Administration broke down the spending Thursday as follows:
-Pre-K (6,500 news positions): $200 million
-Community schools: $38 million
-Rec centers, parks and libraries: $49 million
-Other programs: $81 million
-Fun balance: $24 million
-Park and rec workers (additional 40 positions): $14 million
Democratic Mayor Jim Kenney initially proposed a 3-cents-per-ounce tax on sugary beverages only, but he lacked the votes needed to secure it.
