A lot of them. More than I should but that's OK. Why OK?? Because they are relatively inexpensive and I can afford it.
Many of them are very, very good. Many of them give at least one "golden nugget" and many of them are junk. I very rarely ever ask for a refund.
One thing, though, bugs the hell of of me. WSO's that deal with plugins, themes and software. Most of these WSO's are launched by very reputable IMers. Most of them promise lifetime updates. Most of them are sold with gusto by Warrior+ affiliates.
All good right?
Well, mostly yes, but many times no! Many of them quit working with an update to WordPress or some other change that Google, Facebook, Twitter, etc institute.
Many of them have disappeared if you go back to the WSO access link a few months later.
Many of them do NOTHING to rectify the situation.
Here's one example ( I have a lot of them).
I bought a WP Theme, developer license, for use in my offline business. If I told you the name of the WSO seller you would recognize it immediately. As a matter of fact the seller has put out a new theme recently that has sold very well.
The theme came with lifetime support and upgrades and this as well as the seller's reputation allowed me to install it on numerous clients sites with no worries.
One WP update later, the theme ceased to work. Support questions went unanswered. Requests to buy the developer rights so I could get a programmer to fix it...
There were several other customers who received the same silence. Absolutely the worst support and follow through imaginable.
Change is inevitable but unexpected change (lifetime updates and support type change) can put a crimp in your business plan.
This is one of numerous instances where this type of thing has happened to me.
Anyway, if it's happened to me, I'm sure it's happened to some of you.
WSO creators out there, please stand by your product or indicate up front that the buyer is on their own once the sale is completed.
