Anyone got a longboard, 10 foot plus? How hard was it to find a board bag big enough for it????

I kid you not, I have Googled for it more than once and a few do exist but does anyone know of an alternative to paying over £150? The anoying thing is they do 9'6" for about £40 so I would expect to find a 10'6" for £55 but no such luck!
Black bin liners are just so punk retro!!!!!!
