There are two primary websites for determining where to purchase cheap gas: Gas Price Watch and Gas Buddy. Both sites display an interactive map pinpointing gas stations, updated frequently with individual gas prices.
The problem is the two sites do not necessarily show the same prices for the same station.
For instance, the Hess station at the corner of Prospect and Hampshire Streets in Cambridge is $2.93 on both sites. However, the Shell station a short drive away at 1001 Cambridge Street is listed on GPW as $3.06 and on Gas Buddy as $3.05.
OK, so you will tell me a penny is nothing to squabble over. Fair enough, but look at the Mobil station at 1181 Blue Hill Avenue (at Morton Street) in Mattapan. GPW lists $3.03 and Gas Buddy lists $2.99. Which is it? Clearly, one is not up to date.
Aggregate databases will continue to display data in accordance with inputted content by registered users. But who sets the standards for content delivery? Can anyone update a gas price, or must one be a gas station employee? I didn’t check.
