I bought a hundred onions and sent it to my wallet just after the wallet crawl started. Since they start on wallets with high onions, I hope they haven't been in my wallet before the onions arrives, else it defeated the purpose of the purchase.
Hello. I think they starting from beginning, it doesn't matter how big you wallet is. My guess is you applied recently, so you somewhere in the end of the list

Like me

I had also been worried, some onion bought and sent late.
I was wondering if it would be taken into account but considering that I registered late so everything is cool!!
