i read an interesting article about man made snow the other day.
since a lot of resorts are lacking natural snow they are forced to use prodominately manmade snow... the manmade stuff is very coarse and extremely abrasive on your bases. so this year your bases may get dry really quick (quicker than normal) and to use harder waxes (colder temperatures) since it is much harder for the base to strip from the base.
dont know if its legit but it made sense to me.
if the base isnt taking in wax and its a relatively soft wax (anything that isnt toko blue, which is like <14.) than you should go back to the shop. the softer waxes should be ok. the harder wax it may be an iron to cold problem so if you are trying on a hard wax you may need to try a softer one or use a hotter iron.
