Hey Conor, Only bait i buy is frozen sand eel and razor,buy my razor and squid in Howth in bulk for reasonable rates ,The rest i collect myself,You need to be flexible when it comes to low tide as this is usually prime time for collecting.As round our way said Lug is perhaps the easiest to collect,Takes a bit of practice but worth the hassle,And the same applies to rag .where the best rag is nearly always found at the lowest point at LW and if theres ragworm you can find mussels and cockles .Peeler is an expensive bait to buy ,which is why ive only ever bought it once

Anywhere there is rockpools ,seaweed beds and estuaries ,under rocks etc etc can be good places to find crabs.Limpets can also be handy for wrasse hope this helps

and saves ya a few quid.
