Yes it is nice to have a stock pile. That is what people do when they don't want to run out of juice. How long have you been vaping? If your join date is any indication, you should know this.
It could be my imagination running wild with me as I do not know how many customers Ms. T has or how busy she is on a daily basis...but can you imagine if she did give notice? People would be making huge orders and she would've been so busy she most likely wouldn't have had time to complete them all before she had to move. Not to mention the longer processing times and fewer orders going out due to the amount of juice in each shipment. That would've been a much worse situation (IMO) considering it only took a few minutes for 40 people to place their order on the night that she did open temporarily.
Hopefully this little hiccup has brought a very important lesson to light for many vapers. Stock up. Find your favorite juice(s) and make sure you have a few spare bottles lying around. You never know what could happen. My recommendation is to have at least 6 months worth in stock, but you don't have to go that far. You could just have 1 month, 3 months, or you could go further and have a year. Although I wouldn't really recommend a year, the juice you LOVE today may not be your favorite in a year...sorry, I digress. Anyway, this is not the first time something like this has happened. Remember the time Ms. T couldn't get the correct flavoring? Many companies run into issues like this, Ms. T is not the only one. Life (not the word I want to use) happens! Make sure you are stocked up and you won't have any problems when things like this happen.
