Credit card is the quickest! I've done ACH, Check and Credit and Debit and Credit card got it to me in 4 days (3 shipping), ACH was 8 days, Debit was 5 days and check was closer to ACH for me. Check probably depends on individual bank more as well

The fastest method of payment is a electronic check or debit or credit card. The electronic check takes a little longer as it has to clear, before they process to the shipping department, but that is how you get the cash discount. The debit or credit card goes right through and begins to process to the shipping department. Another way for fast delivery is to look for the fast track items. What fast track means is that they ship the next day or you can also look for next day shipping as well. Hope this helps.
