#6: I kind of like the simplicity here...but we need to be carefull it doesn't look to much like Amazon...but keep working with it...I like the smiley face...please try some more things here...I'm interested in what else you can come up with.
#7: This is very similar to our sample logo on our website...but maybe eleborate on this one by maybe adding an arrow to that sweeping dot image..but right now this looks to generic...simple is good but generic isn't...please work on this option also.
#74: I like this...its simple and clean...but can you try some different arrow elements in the "o"...because the one you have doesnt really capture a refill...but close.
#73: This one has a nice look...but the big green circle doesn't really work...if we are going to have a graphical element that large it needs to add value to the image...like something that represents "trust" "security" or "refill"
