Here's Udyr with the scoop:
The bi-weekly sales announcements have been pretty static for a while. Monday/Thursday is a predictable publishing schedule that players are used to, but we’ve been thinking about a couple of different ways that we could change things up for the better. It’s never fun to open up the fridge every few days only to be disappointed that the sandwich you’ve been waiting for isn’t there.
One experiment that we are going to try for May's sales only is to simply publish the entire month worth of sales in advance so that players can plan for the champ(s) and skin(s) that they really want to buy. This will be the first of a few small tweaks from the ecommerce team to try and relieve some player pain. If it's well-received, we may bring the experiment back in the future.
Please note: the advance notice moves these sales into the category of pre-announced promotions, meaning that we won’t be offering partial refunds on content bought between now and each sale. Mark your calendars!
Below is the entire month of weekly sales for May. If you have thoughts about this change, please let us know in the comments.
