Got the following reply for the service request . Good Day ! Actually , those tanks are on sale and discounted for the next 6 days . Moreover , our production team has the right to remove it on the shop depending on their plans . I would suggest that you purchase the tank while it is still on sale and in the shop as there ' s no guarantee that it will remain in there forever . If you have any further inquiries , or are in need of our assistance please do not hesitate to contact us . You can reopen this ticket or submit a new one . If not , you may close this ticket and proceed to rate us for our service and performance . Your feedback is highly appreciated and will help us in improving our ability to serve you and other users . Thank you ! Best Regards , They do not confirm whether it will remain in the shop or not . just that it can be removed from the store at any time . also they suggest I buy the tank to be safe . No clarity as such but if we really want this tank then it is better to buy it till the offer lasts .
