Consolidated My Items and It Became More Expensive - What Should I Do?

Hi, I'm a first time user here and really need some help!

I ordered about 100¥ worth of stuff and the shipping cost ended up being 340¥. I selected the option where they would take out the original packaging and put it all together and it turned out to be even more expensive than the original estimate!!

I really don't want to pay for this and I'm OK with not having my items.

What do I need to do at this point? What happens if I don't confirm the price of shipping? How do I abandon my package at the warehouse? (I'm from Canada btw)
