1. Being a little more proactive with communication of not meeting delivery/in stock targets.
2. And following up with queries about new products that are not available.
1a. I have no problems with delays outside their control but if they know a product will not be available on the 20th for example despite it being advertised for weeks prior something should be sent out before that day even if it's the day prior/same day and not the customer having to ask days after the expected date.
2a. I launched a query about a new hot product that was due to arrive in NZ. (Not a CPU/GPU BTW). Stock of that product was not available on their site until much later than the competition. Following up with me when they are aware of that product showing with their supplier would be smart. Yes CL some of your competitors do this.
A final note about CL; they still hold the crown of having the "good sh*t" vs competitors (albeit barely), however I find their selection could be better. Brackets/adaptors for various things, more water cooling gear, high end monitors, high end keyboards, mid-high end audio gear would be good to see.
