Brick Owl Seller Review - Brick Takeover

Sometimes you are left shaking your head at how some people can run their businesses.  I'll try not to make this an inflammatory post.  I had (keyword, *had*) an amazing large creation planned.  I couldn't get all the parts I wanted off the secondary markets so I went straight to LEGO.  They completely boffed the numbers, timing, and other factors such that they eliminated themselves.  Off to the secondary markets it was!  So I finally found a German seller who had a good portion of the parts I needed!  Joyous day!  The price was a little more but I was willing to bite.  Then I got bitten.

Order Details
Why this store: Had all the parts I needed.  Verified inventories with the seller beforehand.
Packaging: n/a
Part condition: n/a
Communication: Very good
Feedback left: n/a
Odd telltale signs: n/a
Issues: Yes.  Despite verifying with the seller that his inventory was correct, there was a problem.  Apparently his inventory WASN'T correct.  He cancelled my order and refunded.  I told him it would have been highly preferential to cancel just the items he didn't have instead of the whole order.  But I saw why he acted the way he did.  Once he got his inventory corrected he let me know.  I went to rebuild it only to find that he had DOUBLED the price on the huge quantity item I wanted.

Recommendation
To be sure, Brick Takeover has a high positive transaction count.  I've seen way worse.  But the terms page is a huge blockade of regulations with fees buried in the text.  Other German sellers have much cleaner terms.  Also, given the cancel/price-hike/relist scam, I can say that I find this seller to be less than honorable.

There, I said it.
