You like to make unsupportable statements a lot. I ignore them.
Squadron is great for variety. They used to have a pretty unusable search feature, but it's been improved.
Whether eBay offers "free" shipping or not is semantics. An eBay purchase is item plus shipping equals purchase, period.
Squadron's site will always tell you what it's going to cost up front. They won't be giving you a later refund unless something was wrong.
Be sure to click "recalculate" each time.
