Massdrop again offers the Adafruit PiTFT 2.8" Touchscreen LCD for Raspberry Pi, model no. 83-15684, for $26.49 plus $3.49 for shipping. That's tied with last month's mention as the lowest total price we've seen. (It's a current low by $5.) It comes fully assembled, is designed to work with the Raspberry Pi model A, B, or B+, and features a 320x240 resistive touchscreen with 16-bit color pixels. Deal ends August 6.
Note: It's expected to ship on August 21.
