BBTS pile of loot question

[Starscream77]

Got an "urgent" message overnight from BBTS that my pile of loot has to ship. I just preordered a couple of Nov release figures I wanted in the bundle.

If I purchase something in stock today and add it to the POL will that extend the shipping date a couple more months? Or is it based on the first purchase?

I believe it is based on the first purchase, they set some time limit on how long they will hold the pile.
I had this happen once and i contacted them and asked to delay 2 weeks as i had a large item due in and they obliged so suggest try contacting them?
