The reason being that they only list hostels in major traffic centers, Khosan Rd, Mexico City & the like, where they can get a commission from the owners but out of the way places, even though they are major border crossings, they can't be bothered.
Posted a thread a few months about this subject in relation to Tapachula Mexico, when the lame excuses were removed from the response by the powers that be, it boiled down to what I just stated.
Same happened a couple days ago when looking for a cheap guest house/hotel in Koh Kong on the Thai Cambodia border, only listing was an $80+ resort, even posted a query on BNA forum, 2 views.
Arrived this afternoon, used a tout for the Cambodia E visa, as it appeared that was the way the flow was going, tout then recommended a hotel. Very nice place with pool, free wifi, restaurant/bar, fan room $10. Touts tip was no more than Hostel Bookers charge the hostel.
So in the future I will just stick to the tried & true touts & cab drivers, should I be arriving late in a major city where the booking services deem it profitable to list hostels, I shall just call the hostel myself & request a discount in th amount of the fee.
