FAQ
Frequently asked questions
When does bulk buying actually make sense?
When the price per unit is genuinely lower and you will use everything before it spoils or goes stale. Otherwise the 'saving' just sits unused.
What if the small pack is cheaper per unit?
Then the bulk pack isn't worth it and the tool will flag it. Buy only the quantity you plan to use.
