Absolutely! For each additional Growler you want, add an additional pledge amount to your current pledge. If you got in at the $35.00 pledge amount, add another $35.00 for each additional Growler you want. If you want a Keg Cap Tap system on any of those Growlers, add $30.00 for each Growler you want a Keg Cap Tap.
Example: your original pledge was $35.00 and you would like to order a second Growler. You increase your pledge to $70.00 ($35.00 X 2). You decide you want the Keg Cap Tap on both. Just add another $60.00 ($30.00 X 2) for a total of $130.00.
