I was just going to reply and saw you got it. Nice job.Nevermind, I got a response. They are sending my other refunds. It was pretty easy, as mentioned by Sequoiasoon.
I simply emailed [email protected] stating that the rules didn’t state anything about a limit to redemptions, just that they had to be one submission per unique invoice. Took about a week to get a response.
I looked up Arrowhead Promotions and called the customer service number. I gave them teh details with my receipts, the one per unique invoice details and what BP/Castrol had told me which was I went for the 2nd 10qts to submit.
