The new store has been approved by Verotel and is now working. It is located at https://www.bound2burststore.com/ (or https://www.bound2burststore.com/store/ to bypass the warning page). I suggest opening an account there to test it out, and please report any issues.
At present, the new B2B Store contains only a small number of clips, enough for the required authorization test. For the next month or so, new releases will appear in both the old and new stores, but from the start of May they will appear only in the new store. The old version of the store will continue operating until the hosting company removes php 5 from their servers. I have no idea when that will be.
Over time, you will see titles disappear from the old store as they migrate to the new. The links on the main Bound2Burst website will change accordingly. Some movies will never be transitioned to the new store. I am using sales numbers since 2013 to determine which. Movies which have sold only a handful of downloads over a period of years should clearly be dropped. However, all files will remain available on Clips4Sale, and links on the main Bound2Burst website will point to these where applicable.
