Update on prior update: We have resolved the issue (at least in so far as we can test it with @core's connection.
I would ask that IF you have had a problem with the cart dumping your content or difficulty logging in at any point in the past that you please clear your cookies one last time so we can make sure you have the most up to date data possible.
If at any point you have your cart dumped on you again (I don't foresee it happening but as I said we can't reproduce it on our end), please please contact me directly either by tagging me here or having customer service pass me a note on how I can best reach you and I will personally take a look at the internet service provider you are dealing with and get it fixed asap.
Finally, and just as importantly:
This fix may help slighty if your ISP was slow loading due to the above issue, but please be aware I am continuing on with our planned improvements that were already in the works and we will get ecigexpress.com sped up for everyone.
Currently I am showing we are loading 2-5 seconds faster than most of the other competing sites in our category, but as this issue shows, that may be dependant upon your connection and service provider, but I will strive to get us loading as quickly as possible for everyone everywhere.
Again, I thank you all for your feedback, assistance and patience during this debocle. I must now be off to reward @core for his time and generocity!
