Honey and oats granola bars
Coffee , Ensure
I drank a LOT of Ensure and other similar products last year.
The local thrift store was selling cases which were priced so you paid 1/3 the price per bottle if you bought it by the bottle.
The thrift clearance store has it own clearance isle and there they were theoretically dirt cheap.
They had single bottles, same brand as a case for from Two and one half to Three and quater dollars per bottle.
Some brands do taste far better than others but I never paid attention to which brand was best.
You are supposed to use them as part of a meal, but I never got that in my system.
