I try and stay organized with the gear, and pack things pretty neat when i'm on the go. It never fails. One of the things you'll tend to lose very easily is the Canon Body cap, or even a rear lens cap. Without these you run the risk of dust or scratches. OEM caps from retailers run you about $5 to $6 dollars each coming in around $11 dollars for a pair of plastic caps. Fortunately for me, I was able to order some extra ones from eBay. You can find them as low as .99 cents a pair + Free Shipping. Yes less than 1 dollar, but I opted for a different seller because of all the reviews and paid $1.79 for each pair of caps + free shipping. You can find them following this link.
