Does anyone know how long invoices are good for? I sent a refill request a couple weeks ago and it was approved 2 days ago, but the problem is I’m leaving for a 10 day trip next week. So I don’t want to pay the invoice now and have it ship when I’m not going to be home. Will it be okay to wait and pay it a few days before I’m back home? It’s for BPI if that matters. Thanks!
