During the Netflix investor webcast Netflix CEO Reed Hastings confirmed that they are testing weekend shipping:
"Our growing scale gives us many operational advantages. We’re now up to nearly 60 distribution centers across America and can provide delivery to over 97% of our subscribers in about one business day. This quarter we’ll be testing weekend shipping in parts of the country which will provide even faster service both for those new subscribers who signed up over the weekend and for those subscribers returning movies at the end of the week."
Several readers reported that Netflix processed their movies on Saturday.
