Massive decrease in sales since price increase

Hey I'll try to keep this short. I'm just looking for some guidance if you don't mind!

I've been in business for about 6 or 7 years now with my main product being a "lifetime membership" to my website which contains thousands of videos all organized into nicely structured courses.

I had a good thing going for years at a "too good to be true" price of $69. This price resulted in a ton of sales, but it also resulted in a lot of skepticism (eg. People thinking what's the catch here?).

Many people would join at that price and then later go on to tell me that I REALLY need to raise my price because I was selling myself short (I suspect that many of those advice-givers may not have paid themselves had it not been for the low price though). Despite all of that, this low price point of $69 was resulting in a lot of steady sales.

Well, I took the advice of one experienced entrepreneur who also happened to be a member of my site. Him giving advice was his way of paying me back for all the value he received from my website. He suggested raising the price and also offering some "smaller options" as well...

So I raised the price of the lifetime membership to $159, which is still insanely low pricing in comparison to the value received. I also have several $49 options for smaller "bundles"...each of which is also incredible value.

Well, despite the fact that I have recently just did a massive site update (audio and video updates to everything, site navigation massively improved)...despite the fact that what I'm offering is still insanely great value...the sales have plummeted.

I know that I've asked about this on here before, because I've tried similar things in the past...and I've always ended up switching back to the "proven" $69 for lifetime membership...

However, this is the first time that I have actually stuck with the new model to give a true test of time. I've had this new model running for 6 months now, and I have found that much less people buy at the $159 price. Hardly anyone buys the "smaller bundles" for $49...

I did notice that if I run a sale, where I send out a coupon code to my email list...that sparks some business. However, with the old model, I didn't need to rely on running sales as much because people were just buying everyday at the $69 price.

Also, running sales too often isn't a great idea because my list will eventually stop responding to the sales or become reliant on them...

Now I can easily switch everything back to the way it was before, and set my price back to the one-time fee of $69...leaving it at just that one single option again. However, my concern is that anyone who paid at the higher price over the last 6 months may feel some type of way about that.

I was doing REALLY well (in my opinion) for years...but since making this change, I've been stressed out beyond belief. I've been strongly considering quitting self-employment altogether and just going back to working at a real job again because of it.

I'm not quite ready to give up yet though. That's why I'm asking for advice here if anyone is willing to give some.

That was longer than expected, but thanks for reading!
