What if you sent $10 of Bitcoin to an address and when you go to send it, the fee is $15?
That will be a real problem in the future. So if you want to store small amounts like that, it's best to keep it on a lightning wallet like Phoenix or Mutiny until you have enough to send it all in bulk to an on-chain address.
Try to see if where you are buying it supports lightning withdrawals.
Possible, yes. But the costs of on chain transactions make it impractical. What are your actual intentions here? What do you plan to eventually DO with the sats? The most important thing you can do is keep control over them, and paying transaction costs to do on chain transactions is a good way of losing control over them.
