a. Trying to spend below-average amounts on website product displays, search engineO a advertising, and retailer recruitment/support in all 4 regions, provided it is competitively O o feasible to do so (but in any case exercise restraint in spending amounts well above the regional averages unless the resulting sales gains are big enough to lower costs per drone oa sold).

c. Striving to keeping marketing costs per UAV drone sold in all 4 geographic regions to levels that are several dollars below the industry-average benchmark.
d. Trying to keep the warraby period to 60 days or 90 days (but no more than 120 days), if it is competitively feasible to do so.
