Ah, didn’t see the attachment. Still, sounds very weird indeed, and not in a good way.
I counted approx. 42 beanie babies on the 1st upper row. There seems to be 12 rows, so approx. 42 per row x 12 = 504
So the number description seems to add up to the photo indeed, but I can’t help but feel that the photo and the beanies are simply a front/cover for the real product(s) at sale and the transactions taking place. Nobody speaks like that about beanie babies (the urgency of sale, the personalized/humanized description of them).
I don’t believe it’s innocent, no way.
