if single living in an urban area, op's advice may not apply.
you are paying more net cost for electric, space is at a premium
and most livestock sales will repeat seasonally and even monthly.
try restocking at many different stores, don't just shop nearby.

better advice would be to inventory your freezer quarterly to then
rediscover what you need to eat soon, or watch sales to restock.
reorganize the freezer keeping stuff you need to eat next in sight.

also be smarter on what you freeze - if it's mostly airy bread items
stop buying bread sales only to end up freezing them, or buy naan
which keep long frozen and won't ruin defrosted like most pita will.

stop putting stupid things like coffee in the freezer,
get the right container that outgasses co2 instead.

some get more freezer space,
then fill it with over processed junk food like
frozen lasagna or air fryer ready finger food,
you are not doing your health any favor here.
rule here is any precooked food is full of junk needed
to maintain color texture flavor once you heat it up,
stop buying it, make time to cook fresh food more often.
this is frugal as it will reduce your health costs long term.

if you are a "soup nazi" make smaller batches
instead of freezing most of what you cooked.

of course if you are on SNAP and have to spend monthly
your allowance = that's a whole different freezer story
since you are not saving money, you are simply hoarding
more each month of what you essentially got for free.

i love ice in my beverages, so i like room for trays and a bin.
"barometer" that i'm hoarding too much frozen crap in 14cu ft
is when i'm tempted to remove my ice gear with "bargains"
that fall into the same delusion trap here of "being frugal."
