To late! Boycott already on.
I'm also a COSTCO member.
COSTCO made the right choice putting Dinesh D’Souza’s book back in their stores. Give them credit. Liberal elites would never shop at a 'big box' store like COSTO... and when I shop there I seldom see blacks. Democrats don't shop there in large numbers. Their customers are Republicans.
COSTCO gave the finger to the majority of us... and NOW they've reversed that position. Good for them. Time to move on... it's OK again to shop there again.
Money talks. Get the book somewhere else.
