uhh
do they check it often?
do you now want them to find out about the socks?
if u make an account (anywhere), usually they send you dumb promotional emails every so often, and also an email or two every time you order something. you may also get an email once the package arrives.
if they don't look at ur computer, you can make a new email address and then use that. but honestly i would try not to keep too many secrets like that from them. they may find out eventually too.
if they don't check often, you can just delete the emails (and delete from the trash bin). You can also not subscribe to promotional emails and stuff if they let you. but beware you may get random emails like "yo, check out this thing that's 10% off or some crap" or "yo, we just launched a new sock collection, check it out sis!" etc.
i can guide u through ordering the socks, tho u may need to send screenshots or tell me what's going on, since I'm not gonna be ordering socks rn too. but generally e-commerce is similar across sites.
(if ur on a computer, u can send partial screenshots. at least in windows. probably mac too. idk abt chromebook. or u can crop them.)
(pls pls pls be careful with screenshots especially since u'll be on a shopping site. i.e., make sure ur info isn't in the screenshot.)
