No. You can't buy a HOP on Howrse without opening it. It is impossible.
You buy them in the auction or Private sales, or win them as a prize like now they have world tour.
After your 50th day on howrse, and every 30 days after that, Howrse lets you buy 1 pass with 20% of your eq.
Buy them from the sales, you would probably need a few million e if buying from the auctions or 15-20 passes if buying form the PS. Also howrse sometimes has promos where you can win them in a HOP or by buying howrse cards. Also add me on howrse, im AMMMYAMMMY :)
No, you can't, only in the EC.
No, You Cannot Buy Eggs On Howrse
If you buy passes, you have to put in your debit card to pay for it. You cannot buy passes without a debit card.
you can't end of story
You must wait for the 30th day you log on to Howrse to get a karma point. Every 30 days you log on to Howrse, you get a karma point. If you want to get more karma points without waiting, you must buy passes (without using your reserve).
You can no longer buy Howrse cards

You can't get a unicorn when you first sign up on to howrse. You have to buy unicorns at acutions or direct sales.
