Hi there and thank you for your message.
I can definitely help! Yes, you are correct. You need the LC980 cartridges in your Brother DCP-375CW printer. You can find all the different options on our web page here:
https://www.tonergiant.co.uk/model/Brother-DCP-375CW-ink-cartridges/.
The TonerGiant brand multi-pack containing all 4 colours is at the top of the page, the second product is the original Brother multi-pack and each individual colour ink is listed below those two (in case you prefer to buy just one colour rather than all colours).
If you need any help at all, feel free to call us on 01942 880020 and we will be happy to place the order for you over the telephone if you feel that would be easier for you. Thanks, Stu.
