I got some for USD $0.50 each about a year ago, wondering if there are any coupons or similar out there to get the price down from the ~$1.00 USD mark.
MRsDNF I have also had the locking tabs break on a couple of these. Normally they are basically busted in shipping when this happens and just fall off on first use.
If they arrive in good condition, if I dont mistreat them they dont seem to break.
As I say, I got a few at about USD $0.50 delivered some time ago, but now the going price seems to be $1.00 USD or so.
