There are plenty of stores in Finland selling fishing tackle including shops specializing in tackle, outdoor & adventure shops and general shops / supermarkets stocking a range of fishing items.
The majority of the fishing done in Finland is lure and fly fishing. Coarse fishing is not a common activity and hence it can be difficult to find coarsefishing tackle & bait. Some of the supermarkets will stock maggots and worms but it can't be guaranteed.
Below are links to shops and online stores that I have used and found to be reliable:
