Verical is having a sale through May 18, 10% off with code MaySave10.
Most of their stuff is sold in bulk but I picked up 16 LT1054 for $1.86 ea including tax & shipping. For me Mouser would be closer to $3 each with shipping.
The sale code is entered on the last order screen, there's a link above the "place order" button. I had to ask for help to find it :-[.
