Any suggestions on how to keep this service affordable would be appreciated.
Call the sales office a week or so before
your promotion ends and try to negotiate having the promotion period extended. If they won't budge, then tell them what you can afford dollars wise and see what package they will offer you, hopefully at a reduced price.
Make sure you do this before the promotion ends as from what I am told the price increase is applied automatically and I would image it might be harder to haggle once this is done.
I'm in the same boat BTW. My promotional pricing runs out at the end of this month.
