I have some vans messenger bag I got for $20. haha. it kinda works. For everyday riding I hav my lock, multi-tool, Topeak pump, couple wrenches, allen set, tire levers, and a chain tool.

I need to make some pockets to keep it a little more organized, but I think it could get the job done for now.

I'm not going to need to use it for grocery shopping and stuff right now, just back and forth to work. Hopefully if my schedule keeps up I'll keep working during the day, but its hard to say with retail...
