Hi dg91, please give the Fan Edit / Preservation Forum Rules and FAQ a read, mate.
You’ll need to own the official retail release to adhere to our rules if you are going to do a fan edit or two on here. We are not pirates - nor do we buy or sell rips of the official retail releases on here.
It may be worth checking ebay, charity / pawn shops, CEX, music magpie, and any online sales etc for a good deal on the 2020 AOTC & ROTS blu rays.
As of right now, the 2020 Skywalker Saga blu ray boxset is up on ebay UK for £39.62 - and there may also be deals for the AOTC and ROTS individually on there too (a very quick look has them available for around a £5er each).
Edit: CEX has the 2020 Skywalker Saga blu ray boxset for £35 (and when the physical shops open in the UK on the 12th April your local CEX may well be worth checking for individual discs as well).
Good luck with getting them - and for your edits too. 👍
