I'd say **** it, and buy Kivas you should of bought it when they had it, so stop complaining.
1) He said he's new to buying stuff online. The fact that he said he's NEW to it means that when they
were in stock, buying them was NOT really an option for him (possibly because he didn't have money or because he did not discover Toku/Sentai until just recently).
2) He wasn't asking about Kiva merchandise. He was asking about Den-O merchandise.
3) His question and concerns are understandable considering under the circumstances and his inexperience with buying stuff online.
Bottom line, he was NOT complaining. You do not have the authority nor is it your place to say that he was. No action will be taken against you this time, however if you continue to step out of line like this again you will be issued Infraction points.
