Your price could have changed for a number of reasons.
If your price changed after your Dolly started, your Dolly may have been adjusted by your Helpers. This is due to the requirements of the Dolly--things like the items being moved, or the locations of pickup and delivery--changing.
If your price changed between getting a price and booking your Dolly:, the price might have changed due to demand. Similar to airlines, we offer dynamic prices that change based on demand.
