Just a brief note:
When selling inkjet cartridges make sure you show the best used before date on your listing. I have purchased a couple of ink cartridges where the seller has not done this and they have been out of date. Whilst most cartridges may work fine past their date the buyer should be made aware of what they are buying.
One of the sellers I bought from was a genuine mistake and offered me a full refund.
The other seller got a bit stroppy that I had the audasity to complain that the cartridge was ot of date and left feedback that I was an awkward buyer. Well Mr thriftybuys4u, it's not because I'm awkward I complained the cartridge was out of date. If you had been honest I would not have complained!
