Not cheap

Martial arts lessons are not cheap.

Usually you should expect to pay for some (or all) of these items:

1. Monthly tuition fees
2. Annual membership
3. Affiliation with a third party organisation/federation
4. Insurance
5. Licence
6. Competitions
7. Grading (usually quarterly)
8. Uniform
9. Patches/badges
10. Equipment/weaponry

Many classes expect new students to buy a uniform within a month of starting a class.
The new starter is also asked to pay annual membership, insurance and commit to a monthly standing order.
