yea I didn't think those were the original prices, I think the ethnic rider was listed at around 2k. Not sure if the attention is worth the money lost since new users will quickly find out that those deals don't really exist.
Also, the thing I mentioned about using a towel to correct your posture really works. Put a rolled up bath towel in between your mid/lower back, wherever the concave is, and the back of your chair. Way more comfortable when sitting for long periods and prevents you from slouching.
