It's funny I would totally agree to do everything in writing, but I was so anxious after a year of waiting to have enough money to pay them or negotiate I called them first. Most were a year or older so I figured they would be more receptive to my offer since they have NEVER gotten me on the phone or gotten any contact from me before. Some said no but I persisted and asked to speak with a manager or found theCEO email address and gotten a same day written offer. Commonwealth said yes immediately over the phone.
