Are the old Bantam Spectra editions of the A Song of Ice and Fire books out of print?

Before Game of Thrones became part of mainstream fantasy popularity and the HBO series or whatever, they had these shiny minimalist covers for the longest time. Below is an example in the link.

After the show came out, these were hard to find. Now the covers are plastered with HBO ads or Sean Bean.

It seems like a petty complaint, but I hate it when a book becomes a movie or TV show and they change all the covers to posters and ads. I got into the series a year or two before the TV show came out, and now I can’t continue having a nice, uniform presentation of those older Bantam Spectra editions. I got cut off after A Clash of Kings and can’t find A Storm of Swords, A Feast for Crows, or A Dance with Dragons in the same edition.
