Ok, I already went to Ikea Rothenburg, and would like to share my experience, maybe it's useful for somebody else
I had a list of items to buy, used the ikea.ch online "merkliste", basically you can add items to a list that you can later print, there's a small picture of each item, the code, and the shelve / isle to pick it up from
I went to the customer service part with the list (first thing I did), and the was lucky to find one guy (out of 3) that could actually speak english
the guy told me that he could not deliver any small items, just big or bulky ones.
one funny side anecdote: they included a bed sheet set in the delivery, but not an ironing table. how a sheet set is bulkier than a ironing table on their logic is incomprehensible to me
anyway, back on the main topic. I had to manually buy the rest of the stuff (mainly dishes, cutlery, pans and bowls, etc) and take it to the cash. he also gave me a separate invoice for the rest of the stuff, to be delivered within 2 weeks. That was the earliest delivery date possible. He let me chose between friday and saturday, but not the time of that, for that they will call me on the same week to arrange it (or just to inform me about which time they're coming, not sure about that).
so, bottom line:
- 2 weeks delivery for 100% stocked items that you could directly pick from the shelve and get it right there (if you're lucky to have a car, or want to rent one of their vans), to a less than 20 minute ride location.
- they don't deliver anything smaller than a chair (with some weird exceptions)
