With Christmas soon upon us, the time to order E-Stim before Christmas is NOW!!! However if you like to leave things to the last minute, then the order cutoff dates are
US Orders 2pm 12th December 2018
EU Orders 2pm 17th December 2018
UK Orders 2pm 20th December 2018
Orders placed after these dates will still be shipped, but are less likely to arrive before Christmas.
And please remember, even if you order before the cutoff, these dates are not guarantees, during half of Christmas postal services seem to get bogged down with orders, so ordering sooner is always better.
