The same thing happened to me early April. I contacted Ron and he assured me I would only be billed once, even though I had to enter my card info twice.
Quote from Ron of lr
HI Steve, "Ron of Triton" here. No you will not be billed twice, we received your payment for forty lbs. of Keys LR. I know our store front and web are a little weird, but we have a new more efficient web and store front on the way. Thank you for bearing with us.. Sincerely, Ron.
I was a little concerned at first though.
