Does anyone buy packs from Amazon?

All my local GameStops have been sold out for a long time and I’ve bought some direct from Cardsmiths website, but shipping is so slow there. Anyway, I started buying from the Amazon seller 3 weeks ago. I’m on my 9th collector box from them without a numbered card. Obviously I understand it’s possible to be that unlucky, but has anyone bought from there with success? I have my 10th pack coming from them tomorrow, so we’ll see if the trend continues.
