# Manual Allocation
if you turn on this feature , buy -> get behavior will change as the following example
lets assume you have a promotion : Buy 10 from product X and get 2 for free from product X
then you have added 60 items to cart .
in this case (manual allocation is turned on) you will see your 60 products in cart and a badge with promo available to select additional products to apply your promotions .
which is 12 from product X
if Manual Allocation option is turned off and we have the same promotion .
then you have added 60 items to cart .
you will see 48 of product X and 12 free from product X.
to summarize it up automatic allocation will apply promotion automatically which is preferred option for most of companies . If you feel uncomfortable with the behaviour turn manual allocation to on .
