Buying feedback and buying items you want and getting feedback are 2 entirely different things. It's often suggested to new members with 0 or low feedback to buy a few cheap things from a few Chinese sellers (1c-$2) to gain some feedback. They can then resell those items if they wish. Chinese sellers nearly always leave feedback, so it's a great way of earning a few points.
That is different to sellers selling feedback, whereby you pay $1 but don't actually get anything for it apart from a feedback dot.
You will more than likely be subjected to PayPal's 21 day hold, which lasts for 3 months. If you upload tracking numbers into PayPal as well as eBay, they should automatically release the funds within a few days of tracking showing as delivered. If they don't, a quick phone call will see them release it while you're on the phone. They only require the tracking number so they can check.
