Lexmark Cartridge Rip-off

Lexmark Cartridges are an absolute rip-off.<br> They produce a 100XL and 105 XL cartridge. These cartridges are virtually identical except in 2 respects: <br> 1: They have different chips, <br> 2: They have hugely different prices.<br> The 105XL costs R299 for 4, or R74.75 for one, and the 100XL costs R599 for one, EIGHT times the price! (Prices as marked in a major retail group)<br>
