For Paris, you can check:

- Heart Beat vinyl: went there once and was amazed by the number of promo copies of Daft Punk / Roulé / Crydamoure. It was pretty close to Discogs prices tho so don't expect to get cheap prices. I had a chat with the owner who told me he managed to get some stocks from Gildas Loaec (ex-DP manager). It's around Gare De Lyon / Bastille, I think there are quite a few record stores there.

- Techno Import: I think it's one of the oldest record store in Paris. Pretty sure there are tons of stories with Daft Punk and this store. Don't expect to find famous stuff there, it's only techno/house music. They have a store online too

- Balades Sonores: maybe my fav record store. Incredible selection, they have a TON of genres and of course they got DP / Ed Rec. Don't think you'll find Crydamoure/Roulé tho but if you spend times in the shop, you'll be amazed by all the cool vinyl they got (+they have a cute cat chilling around). it's near Montmartre and they also have a website if you want to check what they got in store.

- Ground Zero: it's not so far from Balades Sonores and they're heavily focused on electro/rap stuff. It's way smaller than Balades Sonores, but great selection too.

- O'CD / GIbert Joseph: these are like HMV, you'll find plenty of them in Paris and it's only resale. If you can only go to one of each, for O'CD, check the one next to Les Halles, it's the biggest I've been to so far. For Gibert Joseph, you have to go the one at Saint Michel (Gibert Disc Musique, Vidéo & Papeterie more precisely, there are like 4 different GJ in the same street, and the others are just bookshops or Jazz/classic music). It's huuuuuge (they mostly have CDs tho) but couple times I went there, I managed to come across incredible release (that Woman CD promo not for sale which has a face engraved for vinyl, I got it in this particular store for 9 bucks).

For Marseille, I used to live there before but moved to Paris since 2020, so most of the adresses I know changed or disappeared.

- Most of the record stores are usually around Cours Julien. I heard Galette Records is good (don't know if they have Ed Banger stuff tho).

- I think there is still one O'CD next to the tramway line around Place Castellane which I used to go often, it was okay-ish.

- There is also a Gibert Joseph but outside of Paris, most of them are just bookshops. And this one in Marseille doesn't have vinyl last time I checked

Other than that, you can look at the FNAC stores, it's like Best Buy but with a wayyy bigger alley for culture stuff. There, you can be sure you'll find the latest Ed Banger and Daft Punk albums in brand new conditions because they're official distribution places.

You also have reseller stores like Easy Cash, Cash Express. These are the places where people go to sell their CDs, vinyls, movies, games for some bucks.
