LEGO 10329 and Sony XM5:
eight US and UK listing checks.

In the original observations, the two UK LEGO pages displayed the same item amount. Their delivery information differed in how much we could verify from the page. The follow-up below resolves more of those details. Shipping is recorded separately and does not resolve or reverse an item-price comparison. The US LEGO amounts differ, but missing mandatory checks prevent a verified-saving claim.

The displayed item amounts match. The delivery tariffs differ by GBP 0.55, but that is a shipping difference, not an item-price saving. Because condition and address checks remain incomplete, we do not call this a fully verified eligible-offer tie, rank a winner or publish a checkout total.

The protocol allowed a public illustrative postcode if needed; none was entered. John Lewis’s restrictions put final address confirmation at checkout. We inspected the same product documents’ embedded structured data and labelled it as metadata. No basket change, account, order, payment or personal address was used.

Download the two follow-up rows as CSV, or download the follow-up protocol and evidence as JSON. The original eight-row files remain unchanged.

• Identity before arithmetic. We recorded model numbers, selected colour and package details. LEGO’s nine assembled plant models belong to one 758-piece retail set; they are not nine separately priced sets. The Walmart BM headphone suffix remains unresolved.
• Separate fields. Each row records identity, variant, price, currency, seller, condition, stock, tax basis, membership, purchase model and shipping. An absent field stays unknown. Purchase controls alone do not prove stock for a destination.
• Keep failed checks. Walmart remained in the sample after its page reported no stock. The sample was not replaced with better-looking results. Delivery controls at several stores did not expose readable terms in this session; those gaps remain in the rows.
• No winner without the required checks. None of the four original pairs had every mandatory comparison gate independently established. The later UK LEGO check reduces specific gaps but still does not establish a fully verified eligible-offer tie or winner.

• Monthly amounts beside the full price. Currys showed a full GBP 229 amount beside 36 payments of GBP 9.28. Argos showed GBP 229.99 beside financing from GBP 9.23 per month. Counter-move: record the outright full item amount; do not use the monthly amount as the item price.
• A price beside an unavailable offer. The selected Walmart page still displayed USD 298 after stating the item was out of stock. Counter-move: require a currently available offer in your market before a price can win.
• A free-delivery threshold above the item price. The GBP 44.99 LEGO set did not meet the advertised GBP 50 delivery threshold at either UK store. John Lewis also listed separate collection options. Counter-move: record the charge for the method and destination you will use; unknown shipping is not free.
• Similar names, different evidence. The headphone pages used B, BM and B.CE7 suffixes. The LEGO pages used both Icons and Botanicals branding but shared set number 10329. Counter-move: compare exact identifiers, contents, condition and warranty; do not decide equivalence from a short name alone.

1. Fix the target

   Record the model, colour, size or capacity, condition and package contents before searching.

2. Identify the offer

   Record the actual seller and check stock for your destination. Distinguish outright purchase from financing, trade-in, rental or subscription.

3. Check eligibility and tax

   Establish a matching tax basis, mandatory item fees, membership and coupon conditions. Leave a check unresolved if the page does not establish it.

4. Compare verified item amounts

   Divide each eligible full item price by the count of identical retail units. Rank only after the mandatory checks pass; do not compare across currencies.

5. Keep shipping and evidence visible

   Record shipping as free, a stated charge or unknown. Save the URL and date, then recheck the retailer’s final offer before paying.

• No retailer paid for a place in this sample. Muchita has no affiliate links, paid placement, coupons, cashback or rewards.
• Saved products can retain local price observations when the user refreshes them. Muchita does not supply continuous or backfilled retailer history, scheduled monitoring or price-drop alerts.
• A September snapshot is not a Black Friday discount or a forecast. No observed amount here is guaranteed to remain available.
