Dear @BambuLab please bring back the discount for buying 4 spools +, this gives nice prices, and you are competetive with other filament prices. Without this option, your filament is getting an bit expensive over time. Or - give more spools in the filament membership for discount - 8 spools are not enough 
with best regards, michael
For me it would help to get more colors as REFILLs. To throw spools in trash cause i dont need them is ecological unbearable.
From Bambus POV 8 Spools seem to be break even-point for the membership. More would create more costs than profit
