I was looking around for the best price for a Peak Design camera strap and it seems No Frills (looks like this may actually be RYDA.com.au) has the best price using the 20% and 22% off coupon on ebay. I am not sure what these straps cost usually (it seems like a lot for a strap), but all other shops seem to charge more than this deal.
Peak Design Slide: $76.68 (SVE20) or $74.76 (PLSAV22)
Peak Design Slide Lite: $65.48 (SVE20) or $63.84 (PLSAV22)

Similar to the 'standard' strap but way more useful. Quick release bits and ability to make longer and shorter on the fly is great. Useful if you want length to drop at the hip and pick up quickly but usually that's too long to walk-around generally.
Great strap. Not cheap but I rate it. Pretty sure I paid a fair bit more than (couple years ago).
