OK, typo freaks- that’s “bussels”, not bussels. 
Thanks for clearing that up, Zette. 
Actually, it’s spelled bussels…
Actually, that may explain the discrepancy; small tomatoes will pack closer together and have less air between them. So possibly the packaging mechanism (or humanoid) “knows” that a pint of these tomatoes weighs a certain amount, but since these are smaller than normal…well, you can figure out the rest…
Count me as one who has always been a litle confused by the old “a pint’s a pound the world around” bit.
If they are being sold by weight, as Flashpoint posits (BTW - a grand welcome to ye, madame) why would the sign say the price per pint?
And zette, as you pass the seafood department, could you pick me up a bussel of mussels?
In the spirit of “the customer is always right,” I suggest the only responsible solution is to put one container in your cart, and another down your shorts.
Damnit!!

Woe…Got to be a little careful here. If you consider the packing of a bunch of identically-sized and shaped things and assume they are not squishable, then in fact the packing fraction is independent of their size. While the air gaps are smaller for the smaller objects, there are a larger number of these air gaps.
Now, you may be right though once one relaxes the “identically-sized” and “not squishable” assumptions. I.e., if the small objects have a broader (fractional) size distribution or if they are more squishable (again in a fractional sense relative to their size), then one might indeed find the smaller objects pack to a high volume fraction than the large one. But, I just want to make the point that it is by no means completely obvious if, and by how much, the packing fraction will increase with decreasing size of the tomatoes.
