You can see in the picture, it was $20 vs $32 (I round up a cent). The small bottle cost $26.67 per liter and the larger bottle, $18.29 per liter, or nearly 1/3 less. The other way I’m looking at this is that I get a full liter more for $12 more when bumping to the next size. Sort of like if there were a sale, buy one for $20 get a second one for $9.
- Do you pay close attention to the cost difference between two sizes of the same item?
- Would you have stuck with the smaller bottle in this situation?
- Where do you draw the line? Is it by price or the utility of the item? (Ask me about the gallon of mustard I once bought)
- If it’s a perishable, how long do you stand there and calculate whether you’ll finish it before it spoils?
