I you receive 10 health packs only 1 will be added to your stack. You can have 1000 friends send u 1 health pack each....you'll still only get 1. If 1000 friends send u a health pack and 1 sends u a morale booster you'll get 1 health pack and 1 morale booster.

You are only allowed to claim 1 of each type of pack per day.

If you mean something else then I don't understand and maybe someone else can help.
