Orders/Alibaba 122x32 LCD Displays

Organised by Sci.

The LCDs are here: http://eastrising.en.alibaba.com/product/520361167-212974175/LCD_Graphic_Display_122x32.html

I've been quoted $7.50USD (so about £4.62 each) plus about $35 (~£22) postage to the UK for the 4 I'm after. Price might go down a bit if people are interested. I don't know the price-break quantities though.

Revised postage will be $60, plus $9 bank fees. Across 22 items that's a $3.14 (£1.94) fee per unit. Totals per interested party at the bottom.

Lead time is currently 1-2weeks while waiting for new lot of red backlights. Delivery time should be about 5 days from then. Will be notified.
