My HP Deskjet 400 is 9 yrs old and finding cartridges at the local "Wally World" used to be easy. Now they no longer carry this and the companion color cartridge. After checking other sources in my area and becoming frustrated with high prices, I bought on-line at an extremely low price for 2 cartridges and am well pleased with the results.Keep up the good work!
