THE REFERENCE SHELF
Buying checks

A refill pouch and a bottle need separate contents records
Confirm what is included before comparing quantity and cost.

Keep the received label and lot information
A source observation is not a guarantee that every package in distribution is identical.

A travel size changes the ratio and the offer
A smaller bottle should keep its own size,SKU and price.

Multipack quantity is not a conditioner-only bundle by default
A set may contain different products,not several identical bottles.
