So, i should expect these keycaps on my keyboard hopefully by early September???
I wouldn't *expect* it per se, but you can hope for it. 

  These things are just plastic pebbles in a sack right now.  But, the factory is quoting 5 weeks lead-time after payment.  If payment goes in next week AND they hold to that timeframe, we're looking at early/middle September.  Then, they have to ship to me, I to you, etc.  (I'll do my best to turn my part around QUICK.)  So "September" may be more realistic.  But I'll keep the OP updated with info as I get it. 
 Does this mean the price will go down?  Because if that's the case, I just might order another set. lol
$13 fixed for this group buy.
