Balanced against the greater requirement for some recipes, you get more vegetables per Sack when trading Bundles of Groceries with Nam Ironpaw. Datamined items now show generally 25 veg. per sack up from 5. This is probably aiming at balancing up thing with Farming likely to be in place soon and another source of these.
Worth checking still what you can get hold of more easily and what you will require when sourcing ingredients this way. And the new data is still quite mixed up across the same items so expect some more changes before it settles.
If they do add in the empty containers for ingredients you can buy as they could do (in database not yet implemented), then another option will be to buy your way through it for those with the gold to spare. Example;
Empty Instant Noodles Container
Currently 70s each o Beta from Sungshin Ironpaw that would be 70*20= 14g/Bundle of Groceries/per token.
Seems too low to me so maybe they will adjust number required for lower value items or price (though it needs to be reasonable for levelling purposes also available)
Together with new items that allow you to swap stacks of veg., Meat & Vegetable Traders at Halfhill Market, AH, Bundles etc. it looks like a number of options will be available to help flatten out potential oversupply and undersupply.
