Where can I get a new parachute?

I saw this question, which then sparked mine: Outside of a mission/job, where can I get a new parachute?

Are the locations to getting a parachute different in online play vs single player?

I have had one in my inventory earlier, but I used it when I bailed out of a helicopter. My character doesnt want to reuse the parachute after using it once....

In single player the parachute unlocks in ammunation after you complete the mission minor turbulence.

In GTA Online the parachute (and the parachuting activity) unlocks at level 11. Then it becomes available for purchase at Ammunation.

You can also find parachutes around the map, such as on top of the FIB building. According to Gizmo3k you may pick these up and use them before unlocking them at level 11. Another location is by the cargo ship on top of the loaders and on the large train bridge over the river leading to the Alamo Sea. See here for more detailed information about unlocks in GTA Online.

I haven't played online yet but on the story mode/free roam after you play the mission where Trevor tails the Merryweather airplane and jumps out with a parachute. Parachutes becomes available in Ammunation. They should be on the left most aisle and its the second or third item from the top.

You will also get a text message for all the characters from Ammunation that parachute is available to buy after that mission.
