r/fortnitebr is the peoper place to ask this, you're in the wrong sub, but...

If you're getting the pack now, you're getting 1000 with the 950 if you currently own the battle pass, as well as the crew items for the July pack. In August, if you canceled your subscription you're still getting the crew items but no vbucks, since subscribing for the first month then canceling payment is only paying for the first month, even though your subscription can be active through 2 months. If you ARE still paying for a subscription, you'll get the items as well as the standard 1000 on top of it. The extra 950 is only once per battle pass if you already own it.

Hope that makes sense. Rambled a bit.
