Craterside Supply is a store located in Megaton in Fallout 3. It can be found by going right and following the path as soon as you enter Megaton. The store opens at 8:00am, and the owner Moira Brown's stock, as well as her caps, refresh on Mondays and Thursdays. The shop sells anything one might need, and as most of the Megaton Settlers point out, usually at a good price. Speaking with Moira will give you the option of buying items or starting the The Wasteland Survival Guide quest.
Craterside Supply is guarded by a single mercenary who upon interaction tells you he is watching you, although during her quest he might say, "Leave me out of that girl's crazy experiments. I don't get paid enough for that," probably referring to the help you are giving Moira. Any negative interaction with Moira such as stealing or injuring her will lead to the mercenary engaging with you.
 First floor
On the right upon entry, the counter is just beyond the entrance, with an armored Vault 101 jumpsuit behind it and a locker that contains some of Moira's inventory, but cannot be picked. Moira's terminal (very easy) is directly to the left which contains information on Moira's experiments. Near that is another fully stocked locker which can also only be opened with Moira's key. On another side, the mercenary stands with his back against the wall alongside a workbench and a small opening. Walking through the opening leads to the stairway and the bed owned by the mercenary.
 Second floor
Going upstairs leads to a small living room which contains only a sofa. The opening in this room leads to Moira's bedroom, which contains with a hard locked desk and Moira's bed.
