Well it depends what your budget is, those two combinations are tough combinations with letter that may not be conducive in the .us ext meaning are there a lot of acronyms using those two domains. Now .info and .biz benefitted from the buyout that elequa did giving kind of a min value to those two extensions. Plus the fact they are world wide ext's where as .us is not. If you notice most of the LLL.us for sale in forums are ones that have the ugly 8 (jkquvwyz) and alot of times they have 2 there are cases where one works Q at the beginning can be quality,quarterly, w weather, weekly, etc... Problem is when these letters are in the middle becomes very hard to find uses for them in the .us ext especially. If you look at the good letters they sell for a min xxx just ask DB, I got lucky selling PKR with a K in the middle just lucky theguy wanted it the way I regged it as PoKeR but if not there would be no other takers really, but PSR all good letters would have been an easy sale. But if you can hold them hopefully the min wholesale value picks up for .us and you can get $25 to $30. Hope that helped .
