I spent over $200.00 on the Tienda and Juga components. They will turn around and say the software has bugs and is in beta. I even paid $20.00 more then I was suppose to pay for support.
My big issue was the time between support tickets... way too long.
Also when you look at their stats of what the cart can do it looks perfect. Subscriptions, coupons.... but remember it's in BETA so it is not all true!
Dan is VERY right - Tienda is still in Beta. And we strongly encourage EVERYONE to give it a test before you make it live (it's completely free to download and test even the latest 0.9.0 version).
Unfortunately, we can't make everything work for everyone during the beta process. Even in the 0.9.0 version, which is MUCH more stable, there are still some known features that are not 100% functional; however, the core system is working for a number of people and we'll be resolving the remaining issues soon.
Also, we did respond to Dan's requests promptly (usually within 24 hours each time, over the course of a week - even when it went into a holiday weekend). However, some of the issues that he raised were valid bugs in some of the non-core features of Tienda that have taken some time to get addressed.
ONE KEY REMINDER - please do NOT try to install Tienda (or any major extension - esp. eCommerce) and expect it to work exactly as you envision in a very short period of time (that is especially true for any beta product). PLEASE download Tienda and give it a try on your test server. Put it through it's paces FIRST before you promise it to a client. And IF you do run into problems, please report them on the forum or in the bug reporting area so that we can address them.
